With a barrel length of only 8”, this BANSHEE™ Mk4 is the most condensed size .300 BLK SBR CMMG® makes today. Originally designed specifically for use in M4/AR15-pattern rifles, .300 BLK has often been compared to other popular intermediate cartridges like 7.62x39mm. Where .300 BLK stands out is in applications where other rounds suffer ballistically such as shorter barreled firearms, suppressed use, and subsonic cartridge loadings.
Available in a variety of cerakote finish options, the BANSHEE series represents the most innovative AR SBRs available today. From the quick deploying B5 Systems Bravo Stock, to the stylized receivers and EML™ handguards, every BANSHEE is tailor-made to be the personal defense weapon you can always depend on. With full length M-LOK® slots on both sides and the bottom of the handguard as well as M-LOK between the top picatinny rail sections, you’ll always have enough space for those must have accessories.
The AR15 platform is well known for its capability for customization but picking the right parts doesn’t have to be a nightmare of homework. Everything from the B5 Systems Bravo Stock to the full kit of ZEROED parts and accessories are made here in the USA with quality and attention to detail that is second to none and each BANSHEE comes equipped with a slew of ZEROED parts standard, including:
