First post and my first build

[Grendelsnap]

Hello all,

51101

First one I've ever assembled from scratch.

CMMG MK4 Lower
Stag LPK
7075 milspec 6 position tube
Geissele G2S
Aero trigger guard
Magpul K2
B5 bravo
Ranier stripped upper
FN (Rainier branded) CHF 249 1/7 chrome lined, mid-length, modified profile 16" barrel
BCM bolt/carrier
BCM MCMR 15" rail
BCM Gunfighter Mod 0 comp
BCM Gunfighter Mod 3B charging handle
TA31F Acog
LWRC Diopter BUIS
VTAC original sling

I've put the better part of a case through it since last weekend, and it hasn't missed a beat. Very mild shooting rifle. I'm getting good groups with loose packed Lake City, and just ordered a big cross section of "match grade" offerings to try and find out what it likes. I really just wanted to build a shooter based around this barrel and the Acog. I hope it gets to see a lot of rounds on steel in various formats.

Anyways, just wanted to say Hi and introduce this little carbine to the world :cool:

Cheers

Welcome. Looks like a good parts list to me.

[Grendelsnap]

Thank you guys :)

Nothing special, she's just a shooter.

You got quality parts and wont regret it.

Black Hills MK262 for the win! I was getting 1" ten shot groups with called flyers out of both a floated stock 6920 barrel and this.

Beautiful ammunition.

Very nice build from a quality parts list. Congrats.

Thank you.

After living with this setup for awhile, I have to say, I'm really liking this BCM carrier group. The finish is glass smooth, the chrome lining and machining of the gas chamber area is immaculate. It cleans up easily and has nice even contact marks with the upper. Overall a very smooth, well made BCG.

2600 rounds through it since completion. No stoppages of any kind with lancers, pmags and GI. Mostly loose packed Federal and Wolf Gold.

MCMR gets hot after 45 minutes of drills, but that's hardly unexpected. . .

I’m a big fan of the BCM rail covers. Magpul makes some good ones too.

That's a lot of shooting. I wish I had more time to shoot.
