Description

CMMG® MK4 BANSHEE™ 300BLK SEMI-PISTOL PISTOL

Compact and capable, .300 BLK was designed to be right at home in AR15-pattern firearms like the CMMG® Mk4 platform. Originally created for optimum performance in subsonic, suppressed, and short-barrel applications, .300 BLK, in supersonic ammo loadings, has evolved into a popular competitor to other intermediate cartridges like 7.62x39. No matter what the application is, this BANSHEE™ is built to fit the bill.

The BANSHEE series represents the most innovative AR pistols and SBRs available today. From the quick deploying RIPBRACE® 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.

Mk4 ZEROED parts and accessories – Quality comes standard

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 RIPBRACE 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:

  • ZEROED Pistol Grip
  • ZEROED Drop-In Trigger
  • ZEROED Trigger Guard
  • ZEROED 60°/90° Ambi Safety
  • ZEROED AR15 Ambi Charging Handle
  • ZEROED Ambi Mag Catch
  • ZEROED Extended Mag Release Button
  • ZEROED AR15 Bolt Catch
  • ZEROED AR15 Polymer Dust Cover
  • ZEROED Linear Compensator 308 Win
