I'll probably replace it with a LPGB.

From my own experience, modifying the existing fsb into a low profile gas block is preferable. It costs nothing and results in a more solidly mounted gas block.

Mark, if you assembled the lower yourself, did you verify that the magpul stock was civilian or mil spec and the buffer tube was civilian or milspec? I learned the hard way that not all tubes are identical nor are the stocks. The difference in width could be the cause of your rattle. Just something worth checking on.

Yeah, they’re both milspec. The buffer tube and stock came together in a LPK kit. I did assemble it. I guess it’s just a rattley stock.

I just got back from the range with it. It runs great.

You could definitely do that. If that one is pinned on, it is going to be completely secure. And removing those pins can be a real bear.

Be aware that they are tapered pins, and will only come out one direction. Off the top of my head, I can't recall which way they come out.

I can ask the guy who installed them.

Be a shame to cut down a DD fsb.

That’s not necessary. You can see which way they go.

Nice lil rifle.
That grip went on all of my rifles, the XL fat one.

The stock needs shims to not rattle, I just shoved cardboard in it for the single time that I used it. PSA LPK.
I wound up using the one from my .308, a Magpul SL.
Fit's well and has QD cups.

11.5" or not I didn't like shorty handguards at all.
10" worked out much better for me.
I didn't have a FSB to mess with so it was a simple swap for me.

I'd be hard pressed to not trim it down and use it as it's already pinned.
I wouldn't swap it out for a GB that's attached with just set screws, that's going backwards.

A Geissele GB is about $65 and has a pilot hole to drill and pin it, comes with a coiled pin.

Looks great Mark. How do you like the quad rail? I put one on one of my rifles and it just seemed a little aggressive on my hands. I think at the time I thought I needed a rail on all 4 sides for attachments, not realizing the beauty of M-LOK. The next pistol I built I put a Geissele hand guard on and I loved that.

How long did your stamp take?

Cause that's illegal (even if temporarily stayed?_)

Ummm NO.

Hey I know, you guys should derail his thread with your opinions on braces and tax stamps. We don't get enough of that around here.

Yeah, I kinda sold him on it, I have one on my 6933 and love it. Arc told me something about gently cupping balls or somesuch, but damn if the ergonomics don't just work better. In fact, earlier tonight I bought one for one of my URGI builds and just installed it. Feels perfect now. Fuck overmolded, this is the way. The MOE+ I bought years ago eventually turned to mush all on it's own, at least I can paint these if I want to.

I like it.

And if you need a new gas block, e-mail me! I have an adjustable Superlative Arms Adjustable Gas Block that's yours for the asking. (You just have to post new pictures. )

Yeah, brother. All your advice has turned out excellent. I really appreciate all your help.

Thanks, man. I am rethinking it because it’s ejecting perfectly. I may just leave it all alone.

It’s not hard to shoot or anything. I do like it. I kind of do want an M-LOK handguard but I’m still new (just getting back into shooting and yesterday was my first range day in 18 years). I’m going to settle into this one before making changes. Maybe I’ll practice changing stuff on my budget AR first.

I was trying to avoid mentioning it because some people have been waiting six months. I guess I had nothing to do with the time it took so it was 13 days from submission to approval.

There are many better reasons.

I wouldn't be worried about a FSB regardless of the manufacturer. A cut down FSB pinned to the barrel, is going to be absolutely rock solid. While I have personally used many clamping style or set screw style low profile gas blocks, they are never going to be as solid as one that is pinned. Extra bonus is that the work can be done without removing the gas block.

I could get some bolt cutters like the ones the janitor uses to cut the lock off of lockers at school.

I’m going to spend some more time with it as is. I’ll add a WML and see if I can live without M-LOK.

I have a quad rail on my 6920. It seemed rather aggressive and I didn't think I'd like it, but it turned out I do. It works great for me, especially with a foreend vertical grip. I plan on putting one one my 10.5 incher when it arrives.

ETA: Mistyped...11.5"

A hack saw and a file would be my suggestion, but you do you.

I do have a cover on the bottom rail that makes it more comfy. I may replace it with a vert.

I figure it’s a reversible mod so if I replace the FSB with a LPGB and don’t like it or feel I’m missing something, I can always pin the FSB back on.
