Description
Product Overview
The CMMG Mk4 T is a .300 Blackout semi-automatic rifle configured with a 16-inch medium-tapered barrel and a CMMG RKM11 KeyMod free-float handguard. Its forged 7075-T6 aluminum receivers, single-stage mil-spec trigger, six-position M4-style stock, and A2 pistol grip provide a practical AR-pattern setup for range use and recreational shooting. The barrel uses a 1:8 twist, a 5/8x24 threaded muzzle, and an A2 flash hider, making the rifle compatible with commonly used muzzle accessories. One 30-round Magpul PMAG is included.

I have had this rifle...
I have had this rifle for over 2yrs now and I have not been impressed with its accuracy to say the least. I still like the caliber but I wish I would've just got it in CMMG Banshee form for home defense because that's about all I would recommend it for.
