Details:

The CMMG Banshee is one of the most popular 9mm Pistol Caliber Carbines on the market. It is super reliable and makes for an excellent home defense weapon or PDW.

Here we have the CMMG Banshee MK4 9mm complete upper assembly. This upper assembly comes with a 5-inch barrel made from Salt Bath Nitrided 4140 Chrome Moly Steel, making it durable and giving excellent performance even at high temperatures.

The barrel has a 1:10 twist rifling profile, ideal for a wide range of 9mm bullets and works exceptionally well at stabilizing standard 115 grain 9mm bullets. With the small 5-inch barrel, you can expect a lot of muzzle flash from this upper; therefore, it comes equipped with a CMMG 9mm ZEROED Linear Compensator, which significantly decreases perceived recoil and muzzle flip, improving the overall performance of your PCC.

The CMMG Banshee Mk4 Uppers are different from most blowback 9mm uppers. They use a Radial Delayed Blowback system instead of straight blowback. This allows them to use a lighter bolt and have a significantly softer recoil impulse. It comes with a CMMG 9mm MkGs Bolt Carrier Group, which is compatible with all 9mm AR lowers, whether they use Colt-style or Glock-style magazines. With this upper assembly, you also get a CMMG ZEROED AR15 Ambidextrous Charging Handle.
