MP22 Compact thread adapters

[strobro32]

I called S&W today and they told me they have no plans on making the adapters for the Compact.

I was also pleasantly surprised to hear today a friend of mine at Stalking Rhino Industries is making the first and currently only 3/8 x 24 - 1/2 x 28 thread adapters for the new MP22 Compact. He operates a suppressor company and does highly accurate work.

SRI SS adapters will be black oxide finished and can be thrown into the dip to clean. Easy peasy.

Here is his post at NFAtalk.com.

Hey guys!

Just finalized our thread adapters for the new S&W M&P22 Compact .22lr handgun.

Here's a picture of the product....(we snapped the pic before they were notched for the wrench so that feature isn't shown but will be on the delivered product).




On the left is the adapter built for the Silencerco Sparrow/Spectre o-ring profile, and on the right is the traditional adapter.

These adapters are offered in SS and the cost is $40 apiece delivered.

We are also offering a limited run of 25 of the Silencerco profiled adapters in titanium for $50 apiece delivered. These are first come first serve.

PM or Contact Shawn to purchase one!

[strobro32]

Just got off the phone with Silencerco. SRI is who they recommend for the thread adapter with their O-ring engagement specs.

[strobro32]

Here are some pics Shawn@stalking Rhino posted today.

How do you take of the slide to clean the gun with the adapter attached to the barrel? Do you have to take the adapter off every time you want to remove the slide to clean the gun?

Thanks....

[KEN L]

You can't and yes.

SRI wants $40 for theirs, and it comes SS without a thread protector. I would've had to pay $10 or so to get it Cerakoted black and then another $15 for the TP. Assuming SiCo lists most of theirs at just under $40, so I'm definitely waiting a couple weeks to get the SiCo version.

Smith & Wesson M&P 22 Compact Thread Adapter For Sparrow Blued - $23.00 : EWK Arms

Can't vouch for them at all, but they have the Sparrow thread adapter, blued, with thread protector for $23. $3/$6 for USPS standard/priority. The non Sparrow version is $22. I doubt the thread protector includes o-ring engagement.

You Sir... are a hero. Just ordered one to try it out. Ordered one over two weeks ago from Stalking Rhino and still don't have a time frame for delivery.

I'll post up when received.

If you like what you receive I too will place an order. Hope to have my 22 compact by end of this week. Im sure palmetto has a bunch to get out tho!

[The Galician]

Greetings,

Thread adapter from EWK should be here today it looks like. I received a shipping confirmation about two hours after I placed my order. That is what I call good business. Will post up later my thoughts when it arrives.

Greetings,

Well I am just pleased as pig**** with the customer service of this guy. Ordered yesterday and here today. Screws on with a 1/4 inch allen wrench. I need to get to the range and test it. But you telero... your google fu is unmatched. Thanks buddy.

EWK is a good company but their design is not optimal. I'm going to give an experienced guess that the EWK adapters will foul with lead in a few hundred rounds to the point where the wrenches will not fit. Anyone who has SS stuff vs alloy carbon steel will weigh in.

SRI and SilencerCo adapters will last a few thousand rounds between cleaning. They are a better app. JMHO.

Can you post some pics from the muzzle end? And a pic if it mounted? The one stock photo doesn't show much.

That was kind of my thought as well. Be interesting to see the feedback. I'm holding out for the SiCo.

[strobro32]

Mark McWillis @ TROS is making them now. He makes excellent adapters too. I can recommend him without reservation. $68 shipped
TROS USA

They are available with the Silencerco O-ring engaement front.

[viriceman]

I got my new Compact .22 a week ago and my TROS adapter (Silencerco) early this week. Packing my range bag now with my Sparrow and I can't get the factory thread protector off nor was there a wrench in the box
My plan was to do a SR22/M&P .22 Compact suppressed shoot-off today but I guess the suppressed part will have to wait. This will be my first .22 S&W in years and can't wait to shoot it.

Greetings,

I hold no allegiance to either dealer. Actually still waiting on the SRI one to get here. However, after 500+ rounds through the EWK... sorry, but no fouling to the degree you experienced. Maybe in another "few hundred" rounds.

Greetings,

I was a grunt in the Army so there is nothing a BFH and vise grips can't fix. Of course the thread protector is not very pretty anymore, but I am inpatient and the thread protector was tight as hell.

I actually did a video review with my Brother for another forum testing ammo for a Ruger Mark III Talo. You can see it here:

Dangerous Brothers: Tradecraft... the Silencer Ammo Test - YouTube

1. CCI Quiet 22LR: 710 FPS with a 40 gr bullet
2. CCI Standard Velocity 22LR: 1070 FPS with a 40 gr bullet
3. Aguila 22LR SSS Sniper Subsonic: 950 FPS with a 60 gr bullet
4. Aguila 22LR Super Colibri: 500 FPS with a 20 gr bullet
5. Winchester 22LR Subsonic: 1065 FPS with a 40 gr bullet
6. Remington 22LR Thunderbolt: 1255 FPS with a 40 gr bullet
7. Gemtech 22LR Silencer Subsonic: 1020 FPS with a 42 gr bullet

I used this same ammo to test out the Compact and EWK adapter yesterday. Very, very impressed. No video

Straight out of the box, no cleaning, 500+ rounds. Some notes:

A. CCI Quiet almost fully cycled the pistol. The slide did not go all the way back causing the shell to get stuck in the slide. No big deal. Didn't expect any extraction. Maybe with a cleaning and lube it would fully cycle.

B. Aguila Super Colibri was lethally quiet, powerful and did not cycle the gun. Definitely tradecraft ammo.

C. Aguia SSS worked perfect. 60gr of whoop ***

D. All the rest performed flawless. No FTE, FTF or stove pipes

Was all the testing done with the EWK adapter while suppressed? If yes, which host and which suppressor?

Vise grips worked like a charm

Greetings,

Yes, with the EWK adapter. That was the point. The set up was, M&P22C, EWK Adapter, and Tactical Innovations Stratus Suppressor.

I am a steel person. When it comes to swords, knives, and like arms, I have a solid grasp of steel.

If you want an adapter that is good enough... well I'd say EWK fits the profile. You get a thread protector and same day shipping because they are in stock. It is already blued and I like the Allen wrench aspect for removal... a lot.

I can't speak on the SRI model... YET. I was one of the first to order it and have yet to receive it. I sent my money order off on 2 Sep 14. Still don't have a ship date. But Shawn has been in contact with me and fully explained the delay. So for $28 and to test this pistol I got the EWK also.

If the EWK was the only one I bought... it would have been good enough for my needs. I don't run thousands of rounds through my suppressor a year. If you want a better metal, you will be waiting a bit.

The conclusion from my personal hands on experience is that you can get by just fine with an EWK. YMMV.

GemTech is also working on an adapter for the M&P 22 Compact. I don't have an ETA on availability.

[strobro32]

Twin Tech is making them now. I have no experience with this company.

I think I like that one best so far, when looking at the combination of price and design. I have a spare TP is could use, but they don't have the blued adapters available, yet.

Plus...it's just hard to buy something from a company that sells "solvent trap adapters", no matter how legal they may be.

[ScottS]

I have no attachment to the company in any way, but I can't say enough about EWK Arms, and their threaded adapter for the Compact.

Their customer service is really stellar, they shipped immediately, the adapter is only $23, which includes a thread protector, and they only charged $3 for shipping (no gouging there). I think there are 5 lessons in that sentence alone other companies could learn.

The adapter itself is beautifully machined and finished, and installs conveniently with a hex wrench at the front.











Lots of flash there, but I wanted to show the hex.

This is a terrific option for those who want a threaded adapter.

[BigWaylon]

Looks nice. But, that's the $22 version, right? Not the $23 version made for the SiCo rimfire cans. It's missing the o-ring engagement section.

It does appear short enough you could use it with the SiCo cans without worrying about damage to the o-ring or alignment issues, just not the added benefit of sealing off the threads from build-up.

That's correct. It's the $22 version. Good eye.

I ordered the SiCo version by mistake, and sent Eric a note asking to switch versions before he shipped. I got an immediate note back telling me he'd switch versions for me. I told him to just keep it at the $23 price (I call it the "stupid tax").

[strobro32]

SS,

Please post when you know how many rounds will prevent the allen wrench from insertion. Let us know the round count, which brand/type of ammo and suppressor used. This info could help others decide which adapter to buy.

Thank you.

You seem to think me more...anal than I am. I don't log my guns by round count/brand/which can. I shoot them. A lot.

I can tell you I've already had 100 rounds of CCI Subsonic through the gun, all through my XCaliber Genesis can, since I was shooting in my basement. There is little to no fouling. Personally, it looks to me like there's quite a bit of "room" there, and no real reason to assume the adapter will foul to the point it refuses a hex wrench. I think that "potential problem" is largely the invention of people who have a vested interest in other adapters.

Although this might be an excuse to dump another hundred rounds in the basement tonight. Shhhh...don't tell the wife.

[strobro32]

I'm not a scientist either but rimfire firearms spit lead like crazy. This is what the lead build up from 1000 rounds looks like in a SWR Spectre.



The broached allen wrench opening of the EWK adapter has a .25 inch opening. I'm just wondering how long it will take for .224-.228 bullets build up enough lead to cause the wrench not to fit or worse, a baffle strike.

[ScottS]

I understand what you're saying. I have literally thousands of rounds through my rimfire cans. My point is, so far, only SRI, who has a vested interest in people buying their not-yet-shipping adapter, has brought up this argument. Your line:

The broached allen wrench opening of the EWK adapter has a .25 inch opening. I'm just wondering how long it will take for .224-.228 bullets build up enough lead to cause the wrench not to fit or worse, a baffle strike.

is a direct quote from SRI's comment on NFATalk.

You can see the size of the opening in my last pic. I can't believe that will "clog" too soon. I don't get anywhere that amount of leading inside my other rimfire thread adapters. Most of the lead is deposited on or after the blast baffle. You can actually see that in your picture.

As I said, I have no connection in any way to EWK Arms. No "friends" there. I have no agenda other than to let people know about a useful and inexpensive product.

[strobro32]

SS, I was just asking you to share your experience with the EWK adapter so we will know what happens. Nothing will be as helpful to us as actual experience.

BTW, what you can not see in my picture is the mount is so full of lead that I had to leave it in The Dip for a day to remove the blast chamber.

I checked Matt's measurements and agree with his predictions.
My recommendation for adapters is to get stainless steel (from whichever Co.) and use The Dip. If not, get a dental pick.

[Ballistictip]

Very good info, thanks all.

I order Mine yesterday, Hope they ship it out Monday, I can't wait any longer for Silencerco to make one. It is good they made out of 416 SS , I can dip it without a problem.

[ewk_stuff]

Hi Guys! Eric here from EWK Arms-posting to clear up some of the "issues" strobo32 is raising about the 1/4" internal hex I use on the adapters.

I think the biggest thing would be actual field experience-while the M&P 22 Compact adapter is one I just came out with, I've been making the adapters for the 422 series with the 1/4" internal hex for years-and I can't recall anyone contacting me to let me know about it fouling/leading up. I would imagine if it was an issue I would have heard about it.

Only seen the issue raised on forums where people seem to think it is a problem.

In my opinion, the 1/4" internal hex is a better design for the M&P 22 for a couple reasons-
1. The adapter is a tiny bit stronger. If you mill flats on the .500" diameter portion of the adapter, you'll likely go with 7/16" flats for the wrench. With the .375"+ major diameter of the internal threads in the adapter, you'll only have about .031" wall thickness at the thinnest portion where the wrench flats are.
2. No worries about a wrench slipping on the flats.
3. With the outside flats or the outside hex shoulder, scratches you put on it will be more visible-they'll be hidden with the internal hex.

In regards to the hex leading up and causing baffle strikes-while again, I have not had or heard of anyone having that issue, wouldn't you think an adapter that had an internal opening that is a tighter fit to the bullet be LESS likely to cause baffle strikes? The bigger the opening in the adapter, the more the bullet is going to wander...

In my opinion any adapter that is well made will work fine-this is all minor theory between internal/external hex/flats-while I'd of course love for you to buy my adapter, in the end this is the USA-let the informed customer be the judge.

[WilliamG]

Hi Eric,

Thank you for your response! I'm interested in picking up one of your thread adapters for my (hopefully) soon-to-purchase .22 Compact. I have a question for you:

I keep reading about this O-Ring engagement stuff. I have a Gemtech M&P .22 (full size) thread adapter on the way, which has this O-Ring engagement - to be used on my Specter II.

So:

1.) What the heck is O-Ring engagement?
2.) Does your EWK M&P .22 Compact thread adapter have this O-Ring engagement?

Thanks!

[ScottS]

I'm not Eric, but I can answer these two.

1. Sparrow/Specter II use an o-ring inside the rear of the suppressor to help keep the "****" from blowing back onto the threads of the adapter. Look at the picture in the first post of this thread. See how the adapter on the left has a bare area that extends beyond the threads? That's where the o-ring is engaged to create the seal.

2. Yes, EWK does offer a Sparrow/Specter adapter for the M&P22 Compact. I know because I ordered it in error and had to correct my order.

Thanks for the reply. Just to be clear: So the O-Ring is in the Specter II, and the engagement is in the thread adapter?

So I just get this, and that's all I need?

Smith & Wesson M&P 22 Compact Thread Adapter For Sparrow Blued - $23.00 : EWK Arms

That looks like it has the O-Ring engagement (no threads section) in the adapter, right?

Thanks!

Scott explains the o-ring engagement just fine...but if you want to see some more discussion including pictures, here you go. Just no reason to not get the o-ring version if you're running SiCo cans.

As info, the Warlock II also has the o-ring engagement.

ETA1: The $23 adapter has the engagement section, the $22 does not. Both would work with the Silencerco cans, as the regular one is short enough to not hit the o-ring.

ETA2: yes, the o-ring is in the Silencerco rimfire cans, and seals on the smooth part of the adapter.

I just got the Twin Tech Adapter today, I just put it on, and when I pull the slide back, I can feel it rub against the slide, Its normal or the gun is off Spec? anyone can give me 2 cent? Its any way I can contact Twin Tech?

[WilliamG]

Thanks for the replies, guys. Appreciate the help here.

cmichael - Not sure what to tell you. Where is it rubbing?

[strobro32]

If I in anyway suggested EWK adapters were responsible for suppressor damage, I apologize. Everything I have ever read or heard about their adapters for the 422 series has been positive. I agree with Eric's 3 points.

The question that interests me most is, how the lead particles will react from expanding at the muzzle, into the larger ID of the adapter and then accumulate at smaller ID at the wrench flats?



I personally prefer SS material for my .22 suppressors for the ease of cleaning. If EWK ever makes a blackened SS adapter for the 22C, I will buy and extra adapter from them. He has a fantastic price.

I agree. Lets all buy them from the different companies and compare.

Lower part of the Adapter, The barrel nut is shape concave out, but the Adapter is perfect rounded, When I rack the slide back, I can feel it rubbing against the lower Adapter, Maybe the gun is off spec, anyone here can give me .02 cents?

[ewk_stuff]

WilliamG, The guys here are right on! Can say I believe I only have one of the Sparrow spec adapters in stock-will have more ready in couple weeks though. Stock on my website is current, so if its shows its in stock, you're good to go.

cmichael, I think the best thing to do would be to put the factory barrel nut back on and see if you have any rubbing-that should narrow it down if its the gun or the adapter.

Heya, thanks for the reply.

You now have 0 in stock. And I'm happy. So you can guess who got the last one.

I put the factory barrel nut back on, When I rack the slide back, I can feel the barrel nut and the lower side of the barrel rubbing against it, but If I take the recoil spring out, no rubbing at all, I think the recoil spring put pressure on the front of the slide to goes up few hair, cause the barrel nut to rubbing against the lower part of the muzzle end of the slide.

Going to call up Smith to find a solution.

[WilliamG]

Just to update, I got my EWK M&P .22 Compact thread adapter today, so thanks to EWK for getting it out to me so speedily.

It's interesting to compare my Gemtech .22 (full size) thread adapter to this EWK.

The only major difference is of course the way you tighten the adapter to the barrel. If fouling doesn't become a major issue (which it really shouldn't if you clean your guns even reasonably often), then I think the internal EWK method is potentially less... hazardous to your gun..

I don't know about anyone else, but I get very nervous using the wrench tool that comes with my S&W M&P .22 (full size) when I tighten/untighten either the factory thread protector or tighten/untighten the Gemtech thread adapter. One slip of the wrench and I know I'm going to gouge either the easily-marred aluminum slide or the polymer frame. I know because I've almost done it a couple of times... I don't see either of those things happening with the EWK. Frankly, the allen-key design makes too much sense to me! Time will tell if fouling becomes an issue. If it doesn't, I'd take this EWK design any day of the week over the wrench design.

Either way, let's face it, it's just a thread with a cover, so any of them should do the job. I will say, it would have been nice for an extra dollar or two to see an option of a 1/4" allen key in the package. I don't have a dedicated 1/4" allen key, since I just have a set of allen keys, and I'd like to have a dedicated one for the range bag. Not a biggie, though.

Overall, though, the EWK seems great value for money when you factor in the pricing elsewhere. The thread protector looks high quality, - it screws on easily and smoothly. The idea of spending $68 (which is over 20% of the price of the M&P .22 compact itself - and about 25% of the price some people have been getting the compact for!) is just... sinful. So it's good to see EWK take on a more conservative (read: realistic) approach here.

The only thing I'm missing now is my M&P .22 Compact. Hopefully this week I'll get to pick one up and actually use my new Specter II!
