DETAILS:
The CMMG Banshee 9mm 5" MK4 Complete Upper is built for shooters who want a compact pistol caliber carbine setup with the parts that make the Banshee lineup stand out. It is super reliable and makes for an excellent home-defense weapon, a PDW-style build, or a range setup when you want the control and familiarity of an AR platform with the softer feel of 9mm.
Compact 9mm Performance
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 it excellent performance even at high temperatures. The short barrel keeps the overall package compact, which is exactly the point for a fast-handling PCC build.
The barrel has a 1:10 twist rifling profile, which is 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, so it comes equipped with a CMMG 9mm ZEROED Linear Compensator. That muzzle device helps reduce perceived recoil and muzzle flip, improving the overall performance of the CMMG Banshee 9mm 5" upper.
Radial Delayed Blowback System
The CMMG Banshee Mk4 uppers are different from most blowback 9mm uppers. They use a Radial Delayed Blowback system instead of straight blowback, allowing them to run a lighter bolt and produce a significantly softer recoil impulse. That makes a real difference on a compact 9mm build, especially when you want faster follow-up shots and a smoother shooting experience.
This complete upper 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. You also get a CMMG ZEROED AR15 Ambidextrous Charging Handle, giving this CMMG Banshee 9mm 5" MK4 Complete Upper the core parts needed to finish out a serious PCC setup.
