For more than 70 years .308 Win has been a popular go to for hunters, marksmen, and militaries around the world. With a 12.5″ barrel this BANSHEE may not offer the long-range performance of an ENDEAVOR, but this pistol still packs a big punch like no other. Carrying on the AR15’s reputation for modularity, CMMG builds larger caliber rifles like .308 WIN & 6.5 Creedmoor on the Mk3 (AR-10) size platform, which is based on the LR-308/DPMS Gen 1 high-pattern design.
