With an 8" barrel the Mk10 BANSHEE is built to extract the full ballistic performance expected of the 10mm cartridge. 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. CMMG has adapted our Radial Delayed Blowback system across our pistol caliber lineup to create pistols and rifles with a softer recoil impulse and reduced bolt weight compared to traditional straight blowback systems. Glock magazine compatible. Includes a 15rd Glock 20 magazine.
