Flash Supp?

[Catcanski]

Hi all, just signed up.
But more importantly, I just came back from the S & W store in Springfield, Ma and got a new M & P 15-22, oh and a 1911 (stainless) too.
What I'm wondering is, can the M & P's barrel be threaded using a standard die for a suppressor? Not that there's any flas from a 22 LR but it would look so much better, it looks kind of plain.

Thanks, Dave

Sorry guys, just saw below that you can (I'm new, and excited about my purchases), but can it be done at home or does it require a dedicated gunsmith?

I would not do it yourself. It is quite a bit more involved than just spinning a die onto the end of the barrel.

Dang, you loaded up on hardware.

Surprised the S&W store did not have the model with the flash suppressor in stock. (Unless they are not compliant where the store is located). As mentioned, get it put on professionally. If you or anyone would want to add a can later, it is imperative that the threading be true, or a baffle strike can occur.

Yes, I'm stationed here in Ma. so pretty much everything is neutered. I also bought three lowers, tired of dealing with the state mandated regulations, so I'll be customizing my own...

maxicooper,

does your wilson flash supp need to be indexed? it doesn't look like it but i honestly don't know?

thanks. good looking rifle!

All I want to say is there's a search function for a reason. This has been gone over countless times.

It's been indexed.

since we are back on the topic with a new thread i guess I'll ask my question -

should you have the flash suppressor before you take the gun to get threaded?

 

[Thomas_H]

If the gunsmith doesn't know what the proper threads are for a AR-15 flash hider, then I wouldn't trust them to do the job.

With that said, it depends on what flash hider it is, and how you want it attached. If you want/need it indexed without crush washers or peel washers, then they will need it. If you are getting it permanently attached, then they will need it. Otherwise if you have the tools to properly clamp the barrel in a vice and install the flash hider, then they do not need it.

Anyone familiar with the M16/AR15 and competent to thread the barrel will know the thread diameter and pitch. I just got mine back in a week (including UPS time). I'm putting on a M16A1 muzzle device as there's one in my parts box.

The barrel must be removed from the receiver first.

For those of you that live in a State that requires you to have a pinned flash hider. Have your machinist turn the diameter of the flash hider down to allow the barrel nut to come off. Otherwise, you will never be able to take your rifle apart.

threading when its done right takes a bit of time... the barrel has to be indicated in using a jig to center it on the bore of the rifle not the o.d... it usually takes me longer to setup a barrel for threading then it actually takes me to thread it... the only reason i can think of that they would need your flash hider is to index it or if you dont wanna use a washer, he would need it to make the threads to the right deapth(some are more shallow than others) or maybe he just wants it to protect your threads during shippment... all flashiders/comps for the ar-15 platform are 1/2-28 threads and suppressors for the most part in this cal. are the same or use some kind of adaptor(yhm phantom 556)
hope this helps

Thanks that helps, is $75 about right for threading?

 

[straight-shooter]

I paid...

$7.00 to ship the barrel to the machine shop
$49.00 for threading service included the shipping back to me
$10.50 for A2 flash hider and crush washer

$66.50 total

 

[BELT_FED]

sounds about right.. avoid anywhere that "turns on centers" unless they are going to rechamber and recrown the barrel.. i allways recrown because the factory crown creates a sharp edge to the threads so an 11* target crown fixes all that and no i dont charge extra for that and neither should any other company

 

[tacticool22]

Belt Fed has all his facts correct. I have been a machinist since 1981and agree with him 100%

The $49 to Thread AND ship the Barrel back is a Fantastic Price!!

Consider the time required not to mention overhead

unpackage tictocktictock

Prepare the barrel by removing whatever is needed so it can get chucked in and referanced to ID of Bore Center TicTock >>>>>


Chuck it up in the 4 jaw and indicate from Bore
A fair bit of TicTock here>>>>

Make outside dia. cut>>>Thread >>>> Change tool Bit>> Cut Crown cleanly >>>

Remove the barrel from Lathe>>>

Inspect and reinstall what was removed>>>>

Repackage/Write Bill>>

Hand off to UPS Driver and pay the monthly UPS fee when required which amounted to $7.00 from the $49 sent in

Whoo Hoo!!! Smith just made $42.00 Oh shoot! the Overhead thing!!

Look ma!! I made $30 bucks this morning

And that is dang close to it!

So I say again that is a Fantastic Price $49.00

Oh yeah...Congrats on the new AR I wish I had a Smith lower, Might have to get me one now that they seem to be more available around these parts.

well to be total honest if they have any over head at all.. and are doing it for 50 and no shipping they are not taking the time to "do it right" im not saying it wont work with a flash hider but most wont go through the trouble it takes to get it right for 42 dollars yes it will be threaded.. but id bet that they didnt indicate the barrel in for that price.. i do it for 50 +shipping for the guys on here and i dont charge extra to remove barrel or recrown but most place do charge extra for that, but i have no over head other than my time and tooling... make sure you send your barrel to someone that knows what they are doing and will take the time to do it right...

im not saying straight shooters machinist did it wrong for all i know he is like myself and takes pride in his work , im just saying most wont do it right for that price so becareful... hope this helps
