Hey guys I was thinking about replacing the handguard on my 15-22. I just wanted to ask if I know of everything that I need:

-Handguards
-Free float handguard converter (tacticool22)
-Shoowrench (where to buy?)
or
-Barrel nut wrench (tacticool22)

And one last question: Would these handguards work?

AR15/M16 - Handguards & Free Float Tubes | GunAccessories.com

The first pair

im very interested in this aswell, I want the MOE-handguard but im too scared to start it and dont know what i need.

For the two piece hand guard you will need a front sight or gas block with a hand guard cap and a delta ring assembly to screw onto the converter.
AR-15 Barrel Parts - Black Rifle Works is a good place to start.
If you want the free float hand guard, all you need is the converter.
I have the professional wrench and the hobby version wrench end.
Vise jaws are recommended.

tacticool22 hit this one on the head. You can't go wrong with his free float adapter. Here is mine with a MOE handguard. I used a clamp on quad-rail gas block, but am ging to switch it out for an A2 front sight from True Sight Technologies.

shawnr5...How did you get that Magpul UBR to work with the 15-22? Every resource i looked at ( including Magpul themselves) said it was not compatible so i went with an MOE stock....

That stock is the ACS not the UBR.

I'm too cheap to buy a UBR. I'm running the mil-spec ACS on both my AR and 15-22. It's very comfortable, locks up solid and only set me back $130 each. If I could find a way to convert the receiver extension, I'd love to set it up with a UBR and a VLTOR CASV-EL

my mistake...if i pick up a second 15-22 ( which i am tossing the idea around) i might have Dad take a look and see if its possible to modify it for a UBR

Seems pretty complicated, is there any machining that needs to be done to the delta ring assembly? Also I don't know how I could make the hand guard cap fit because isn't the barrel diameter like .675?

It's not complicated at all and the only machining necessary is the fabrication of a spacer. Tighten the free float adapter. Next, thread on the barrel nut/delta ring assembly. Next, I put my handguard in the delta ring and slid the handguard cap into place. I installed my gas block so that it was against the handguard cap and removed the handguard. Once the handguard was removed, I moved the gas block back a little bit (maybe 1/16") to increase the tension on the handguard. Since the barrel is smaller than an AR barrel, I had to put a socket head cap screw through the handguard cap, into the gas tube hole in the gas block. This screw stopped the play that the handguard had when first installed. Feel free to ask for clarification on any of the steps, if necessary. There's no need to learn by error the lessons that others have already learned. Order the adapter from tacticool22 and the handguard of your choice and set it up exactly how you want it.

What shawnr5 said.

Ok so I would need the delta ring assembly, the tacticool22 barrel nut adapter and the wrench, a true shot technologies a2 sight post (as the gas block), a hand guard cap (still not really clear on how to make it fit you explained it well though I'm just not good at this stuff ), and the handguard. Am I correct?

In your case the wrench Shoo and I offer are just to remove the factory barrel nut. My hobby wrench version is different, as it is just an end that screws onto a piece of pipe.
You should use barrel vise jaws to hold the barrel and not put any torque into the upper. Just ask Brett248Vista about that. M&P 15-22 Instructional Video Series
You will need a 1 ¼” spanner wrench, with a 3/16” pin to torque the converter.

You're almost there. You will also need a short socket head cap screw or button head screw to hold the handguard cap to the front sight base. Drive the screw through the gas tube hole in the handguard cap and into the gas tube hole in the FSB. If I remember correctly, I used a 1/4-20 x 3/8" screw. You shouldn't have to do any work to the FSB to make it fit. It is made for an undersized AR barrel and machined out to the proper inside diameter for our 15-22s. This wasn't available when I did mine and I used a cheap UTG four-rail clamp on gas block and a piece of brass tubing that I slit and spread enough to use as a spacer between the gas block and barrel.
One of the cool things that this conversion offers is the chance to use a longer or shorter handguard. You can go with a tiny pistol handguard, a rifle length or anything in between. Right now, mine is sporting a mid-length handguard. If I get a chance, I'll take some close up pictures of everything involved when I get home from work tonight.

Ok so A2 sight post, handguard cap .750 dia., 1/4-20x38" short socket head cap screw, delta ring assembly, 1 1/4" spanner wrench w/ 3/16" pin, tacticool22 barrel nut adapter and wrench, and a handguard?

Think I got it this time haha

Sorry it has taken so long to reply. That screw should actually be 3/8", not 38". A 38"screw would make a nice long bayonet once sharpened. You should be able to find one at any hardware store and it shouldn't cost you more than twenty cents. If you can't find one, PM me your address and I'll mail you one. I ordered the front sight bar and will be mounting it on mine as soon as it shows up. Tonight, I took some close up pictures of my setup. I'll post them tomorrow. Hopefully, they will clarify things.

Here are the pictures I have repeatedly promised. They are phone pictures, but you should get the idea. Here is the delta ring with tacticool22's adapter in the middle:

...and from the side:

The quad rail gas block I used:

...and from the back. You can see the brass spacer and the screw in this one.

Thanks tacticool and shawn for all the help I got the delta ring assembly, handguard cap, screw, spanner wrench, and that a2 sight (looks great btw) just waiting on the tacticool stuff and the handguard I got from bushmaster. And shawn couldn't I just tighten the a2 sight onto the handguard cap instead of making a spacer? Problem with the spacer is that I don't have anything to make it with.

You shouldn't have to make a spacer. The A2 front sight you ordered should fit without a spacer. I ordered one yesterday, too. Can't wait to put it on mine. I had to use a spacer with the gas block I used because it was made for the .750 AR barrel, not our .667 15-22 barrel.

Ohhh I thought you had to make a spacer for the handguard cap and could you tell me how to fit all of it together? Like what goes on what I kinda got an idea from your pictures but I want to be sure. The delta ring and the converter confuse me.

The converter threads onto the barrel where the old barrel nut was and then the delta ring assembly threads on to the outside of the converter. The screw goes through the gas tube hole in the end cap into the has tube hole in the sight base and then the sight base is clamped on to the barrel. All that's left at this point is to snap the handguard in and sight it in again.

Hmm ok seems easy enough and I have two things,
1. That screw doesnt fit through the gas tube hole in the sight base
2. Whats that gear looking thing in front of the delta ring?

Thread the adapter on first and tighten it. Then install the delta ring assembly. next, put the screw through the gas tube hole in the handguard cap and into the gas tube hole in the front sight base. Slide the front sight base into place and tighten the screws. Install the handguard and sight it in at the range.

Ok thanks for the help. I'll post the results when the stuff arrives and I do it right (hopefully).

the screw will take some force to drive in to the sight base, it has to tap the hole as it goes in. If you have a1/4-20 tap, you can tap the gas tube hole and then thread the screw in. The star looking thing in front of the delta ring is the AR barrel nut. It holds the delta ring on. Mine came with the delta ring assembly. You're almost there.

Too bad you're not here in AZ. It'd be easy to have you come over and get you squared away. Let us know if you have any more questions.

Wait do I need the ar barrel nut? My delta ring didn't come with one

Yes, you will need an AR barrel nut. If I remember right, the delta ring and wave spring slide on to the outside of the barrel nut and then the snap ring goes in the groove on the barrel nut to retain them.

So just to be clear, I need the delta ring assembly, the barrel nut and the free float adapter?

Yes and something in the front to hold it in place

I got my front sight base yesterday (I only ordered it Tuesday) and I think that we'll have to run a tap through it to get the screw into the gas tube hole. I'm going to pick up a new tap on break today. .50, if you want to send me your FSB and handguard endcap, I'll tap the gas tube hole and send it back to you. If you want to, just PM me. I can't wait to mount the new sight tomorrow and take new family pictures with big brother. I can probably even find a spare barrel nut for you.

Aww I ordered a barrel nut already, oh well. I'm gonna try something else first and if it doesn't work I'll send it to you. It'll be up and running by the end of Wednesday if all goes well (tracked my handguard and it's running late). Thanks for the offer

No problem. I'll take pictures as I do mine. Let me know if I can help.

If you haven't started tapping for the 1/4-20 hole, DON'T. Looking at the sight, we will have to use a smaller screw. I'll figure out which size works best and let you know. I think that tapping for 1/4-20 would remove too much material and would weaken the sight.

10-24 is the size you want. I was able to drive it into the steel sight without tapping the hole first. Make sure to get a socket head, not one with a phillips or slotted head. I'll post pictures later. I have to go in to town and get another carbine-length MOE handguard before I loctite it and boresight it.

Any certain length we need?

1/4 to 1/2 inch. any of those should be sufficient.

I found a screw thats the size but its a philips head screw (flat bottom) and its 3/4" long. Any reason why it won't work?
If it has to be a socket head I could just go into town and get one from home depot

Edit: it goes through the handguard cap and the fsb with no protruding in other words it fits perfectly

I you drive it all the way in, there's nothing wrong with it. I recommended socket head because the allen keys used to drive them are less susceptible to stripping than phillips. Keep us posted on your results.

Thanks, will do

You are going to love the A2 sight from TrueShotTechnologies. I have one of the first ones and they just simply rock. Great choice. Give us some photos when you install it.

Endeavor to persevere. <><

Ok I'm almost done I just need to make the A2 sight a tiny bit bigger because there's a groove in the barrel that's in the way. Handguard, delta ring, and the converter went on easily. I test fired it in my backyard and everything works (thankfully).

Anybody know where i can order a complete deltaring-assembly?

You can order one from that site that tacticool posted on the first page. Be sure to order a barrel nut from them aswell (I forgot to order mine and had to pay another shippng fee).

So i need the barrelnut and the assembly?

(I also ordered the barrelnut converter from tacticool22)

Yea because the housing,spring, and retaining ring go over it and allow you to put the handguard on. This is a good video I used as a reference when doing the delta ring portion of the project:
Delta Ring Installation - YouTube

ok, thanks.

lets recap, itemlist:

ordered:
barrelnut Tacticool22 + tools
A2 frontpost.
handguard

need:
barrelnut
deltaring assembly (wont let me shorten it :P).
some kind of tool for the barrelnut.

Thats it right?

You also need a handguard end cap (get a round one) and a 10/24 x 1/2" screw. The end cap holds the front end of the handguard and the screw fastens the end cap to the A2 front sight base. Just drive the screw through the gas tube hole in the end cap and in to the gas tube hole in the sight base.

still need it with the MOE guard?

That screw that I said I found wasn't the right size actually so I just kinda mashed the a2 sight post against the handguard end cap. It's been working well so far and the handguard doesn't most up and down. I've been shooting a couple times maybe 100 or so rounds through it. I don't have an MOE handguard so I can't help you there sorry.

Yes, stilll need it with the MOE handguard. It is retained just like any standard M4 handguard. I have to take pictures of mine, but the end cap is fastened just like in my pictures with the quad rail gas block. A 10/24 screw will thread into the gas tube hole without requiring a tap. I suggest a socket head cap screw, the allen key won't strip the head as quickly as a phillips screwdriver.
