Military Grade Build

[thompson1774]

I would like to build a military grade M-4 copy. I am thinking of using the below listed parts and a RRA lower. RRA Lowers fit tightly and I don't like the sloppy upper/lower fit. That is the only reason that I'm using them.

BCM 16in, 1-7 Twist, M-4 Upper
RRA LPK
CMT or LMT BCG
CMT Collapsable Buttstock
H-2 or H-3 Buffer

Any opinions to the contrary, or am I headed in the right direction?

Looks like a solid and dependable build to me.

Nothing bad about your choices, but I prefer LMT parts to CMT, and a LMT upper would probably be quicker to acquire than a BCM upper, unless you already have one.

Looks like a good build. I would add a BUIS.

[thompson1774]

True, the BUIS, Optics, sling, and other extras will come along. Right now, I'm just trying to create a solid weapon for work and play. I wouldn't mind using the LMT upper, however they mark their uppers as well as the lower and I already have the lower. I don't the agency I work for will like mutt guns. They are kind of narrow minded.

The good thing about my agency, they aren't knowledgeable about weapons, so without the external markings, I think I can still use it for work purposes...

Ram is right, the BCM uppers are going to be awhile. If they don't like Mutt guns then buy an LMT lower too and use the lower you have for your next build

Pretty sure the RR LPK and CMT LPKs are one in the same so you could save a buck or two there...

I'd see G&R for that new BC group Grant is putting together

Not that there was anything wrong with your choices at all...

You might ask whoever supplies your stripped upper and lower to pick you out
a matching set for fit and color...

If you have your heart set on RR....Brownells has a 10% off sale going on and they do carry the Rock River "Match" paired uppers and lowers...

The code to get the discount is... C1T
