M4 .300 blackout???

[Shrillar67]

Thinkin about getting another AR and would like too go with the .300 blackout this time. Any good starter platforms in the M4 carbine style? I'm a colt fan but can't seem too find anything on them making one. Any suggestions?

Are you going to SBR it?

BCM does make some very nice 300 BLK uppers.

BCM would be my choice for an upper and use whatever lower suits your fancy. Get into it on the cheap and just throw it on whatever lower you aren't using at the time.

I'd like too SBR it but need too fill out the proper paperwork

Start as a pistol, then as you wait you can get used to it.

I really like mine.
Its has the aac 9in upper with a Phase 5 buffer tube and a law folder.

From all i heard the bcm is the easy button

That's the point of my question. If you are going to make it an SBR, then a 8-9 inch barrel is optimal. I have a 9 inch barrel on mine.

I was actually thinking 11.5

What buffer are you all running for the 8-9" uppers. I have one on the way and am curious where to start. Mostly suppressed with subs.

I'm running an H2 on my BCM 9" suppressed subs and supers with no issues

I run an H2 with my BA Hanson profile 8.3" barrel. It's been reliable with subs and supers so far.
