More questions for handguard setup

[Dmacpro91]

Hello. This is my first post on here, (been lurking for awhile). I have decided to swap out the handguard on my 15-22 with a carbine length PTS MOE version and put a (fake suppressor) barrel shroud over the top. Yes I've read through most of the threads on here pertaining to that process.

I understand that I need:

Barrel thread adapter nut
Delta ring assembly
New handguard (Magpul PTS MOE)

Barrel wrench and adapter nut wrench

What I need to know is:

A) Do I also need an ar15 barrel nut?
B) How would I attach my flip-up front sight?
C) What length barrel shroud (4.5", 6", 8") would look best for the carbine length handguard in your opinion (maybe some pics)?
D) I read somewhere on here something about filing some "ears" off of the barrel toward the end of the upper receiver. How does this come into play?

Sorry if I missed some of this info somewhere else in the forum. Thanks for your help.

The MOE is not a free float hand guard. how are you going to secure the other end? Typically, it would be held by a retainer ring that is held in place by a front sight block.

All of this is covered in MANY threads. a quick search for "handguard" yielded 360 results Smith & Wesson Forum - Search Results

To answer your questions:
A) Yes, you need an AR-15 barrel nut. You will also need a handguard end cap, 10-32 screw and a gas block. Get a gas block with a rail-height picatinney rail and you can mount your flip up sight on it. Your gas block will probably have a .750" inside diameter for a standard AR barrel and you will need a short length of brass tubing, slit lengthwise, to use as a spacer.
B) Use a rail height gas block. It will be easiest if it is a clamp-on model.
C) I have never used a barrel shroud. Keep waiting for a response or go through the picture thread and see which one you like.
D) The "ears" to remove are actually part of the receiver, not the barrel. They positively locate the OEM handguard and keep it from twisting when the gun is assembled and the factory barrel nut is tightened.
Here are pictures of my conversion:

What happened to that bolt? ( nasty gouge )

Can't you just put a front sight and block on the barrel? I mean, you don't need to use the block, just tighten it on the barrel?

I don't know, just asking.

I'm pretty sure that the nasty gouge is just a hair. My chow/shepherd mix sheds like her life depends on it.

You need to put a screw through the handguard end cap and into the gas tube hole in the gas block to keep the front of the handguard from wobblingaboutI am running a True Shot Technologies A2 front sight on mine now instead of a flip up sight and am very happy with it.

You mean the little scratch?

I've tried to find the standard round end cap, but haven't been able to find any in stock. Would this end cap work?

No that cap wont work, not even sure what those belong to. you need 1 of these below

I use this one with my magpul handguard.

I will have an entire kit out soon. All you will need to supply is the 2 piece hand guards. The "gas block" will look like a low profile one for the AR. A picatinny version will come out later.

good move.

 

[shawnr5]

I pulled my bolt out and there is no scratch (just scratching on the Wax Tailor cd I'm listening to.)

Now you need the proper charging handle. ;-)

I know. I forgot my password on your site and the reset email never does come through into any folder I can find. I would love to order one of yours and give my Plinker Tactical to my brother. You know I'm a big fan of your stuff, Jody.

I'm waiting for this as well. It'll help the hassle of me having to track down all the different parts. You do good work.

 

[Dmacpro91]

Almost done

I've got nearly all the parts needed to complete this.

Can't wait to get my tacticool22 barrel nut adapter.
