AR-15 Banshee 100 8" Complete Upper Receiver 9mm Black

A Pistol-Caliber Upper Designed for Handguns and SBRs

Differing from its line of Resolute upper receivers, which feature full-length, 16-inch barrels, the CMMG Banshee line of AR-15 upper receivers are available in varying barrel lengths, but they're all well below the non-NFA 16-inch minimum. That means these uppers are perfect for your AR-style pistol or short-barreled rifle build.

Each CMMG Banshee upper receiver designed for the company's 9 ARC magazine conversion can be had in one of three variants: the 100, 200 or 300 Series. The 100 Series is the basic setup at the most-affordable price, but you still get a complete upper receiver, including a charging handle and bolt-carrier group. You'll also get an A2 flash hider and a mil-spec charging handle.

The 200 Series in the CMMG Banshee lineup includes an SV Muzzle Brake instead of the A2 flash hider, but the upper still includes a mil-spec charging handle. If you want a complete upgrade package, go for the 300 Series, which provides an SV Muzzle Brake and an ambidextrous charging handle designed by CMMG. All of the upper receivers include a medium-taper barrel machined from 4140CM steel.
