CMMG 30A12E8MB Resolute MK4 300 Blackout 16.10″ Midnight Bronze Cerakote

Delivering a heavy-hitting .30 caliber round on target, .300 BLK was originally designed around being a subsonic round for use in shorter barrel, suppressed rifles. Additionally, .300 BLK set out to utilize as many M4/AR15 parts and ammo components as possible. Great for home defense and suppressed use in subsonic loadings, .300 BLK has evolved into a serious challenger to other intermediate cartridges like 7.62x39mm in supersonic form. Fitted with the suite of ZEROED parts.
