View Full Version : M&P 15-22 forearm endcap and barrel removal questions

I recently picked up an S&W M&P 15-22 and had a couple of questions.

1) I was wondering if there is any advantage of removing the endcap from the forearm allowing the barrel to free float. I assume that it's there given that the upper receiver is polymer and might not be strong enough to safely support the barrel in the event of a drop or sharp lateral blow to the barrel say, hitting are barrier during a 3gun-style competition. If that's not the case, seems like it might be best to remove it to avoid barrel deflection when applying pressure to the forearm.

2) How easy is it to remove the barrel? I might want to get mine threaded in the future. I prefer to have something protecting the crown.

Thanks!

short answer... the 15-22 isn't really floated since the barrel "sandwiches" the polymer handguard before screwing into the receiver. some would argue that it is kinda "floated," in it's own way -- the end cap itself is loose enough fit that it doesn't really contact the barrel most of the time.

lots of info can be found over on this other forum and in this thread specifically:

http://smith-wessonforum.com/smith-wesson-m-p-15-22/133510-diy-15-22-barrel-nut-wrench.html

you can also order professionally-made barrel wrenches from a couple of sources on that forum.

good luck and enjoy the rifle!

Taking off the cap is perfectly safe and fine. The polymer is plenty strong.

Taking of the bbl requires a special tool. There is a member of the s&w m&p1522 forum that sells them.

If you just want it threaded, you don't need to remove the bbl, just take the upper assembly to a smith and you will be fine.

That's interesting, how would they get it in a lathe?

I have threaded my MP15-22....
Gunsmith has the tool to take out....
I have that special wrench and I believe they sell it for $34 (Total)
If you want it, I can do $20 + the shipping or FTF
Also, teach you how to remove it...
Here is the picture after threading

You should just be able to clamp the upper to suspend it leaving you room to get to the tip of the bbl.
I've got a mill at my buddys shop, maybe ill try it myself and let u know how it goes ;)

Are barrel vice clamps needed to remove the barrel using a barrel wrench?

I may have to dig up an older S&W forum thread but I think a dude who didn't use them really ****ed up his rifle hehe. Lemme check

Here's a link to the tool I use. Available at Brownells. Works great.
