CMMG Introduces 5.7 AR Kits & Guns

    Pistol, Banshee™ 300, Mk4, 5.7 x 28mm

    Pistol, Banshee™ 300, Mk4, 5.7 x 28mm (CMMG)

    CMMG have launched their new 5.7 AR conversion kit, individual parts and pistols. The CMMG MK4 5.7 Upper and a 40 round conversion mag will allow any AR-15 to be converted to chamber 5.7x28mm in seconds. The new conversion kits and pistols follow on from the Banshee Mk57 5.7×28 pistol released in 2018, which used the radial delayed blowback action, but fed from FN Five-Seven mags.

    With the recent launch of Ruger’s 5.7 pistol and the new Speer Gold Dot 5.7x28mm Self-Defense Ammunition it really does seem like 2020 might be the most exciting year for 5.7x28s since it was introduced nearly 30 years ago! I wonder what other 5.7 products we might see at SHOT 2020.

    Here’s CMMG’s announcement in full:

    Easily add 5.7x28mm to your collection.

    CMMG’s patented Radial Delayed Blowback operating system expertly handles this high performance, low recoil cartridge – 40 rounds at a time!
    Plus, the conversion bundle ships directly to your door.

    Items have limited availability so order today to get early access. Most Mk5.7 conversion products will begin shipping mid-February.

    • Holds 40 Rounds of 5.7x28mm
    • Compatible with AR15/M16 Lower Receivers
    • CMMG 5.7 Upper Receiver Required
