The Brownells 733 C7 Upper Receiver, a classic reborn!

Featuring an 11.5" lightweight "A1" profile barrel, 1-7 twist, C7 upper with shell defector and a CAR handguards, the Commando is a unique entry into the AR-15 series. It is a mix of old school and new school, a transition from the M16A1 to the M4 platform of today.

The 733 C7 includes enough modern features to make it a viable "go to" setup, especially for those seeking a carry handle receiver. The A1 rear sight nestled in the C7 upper receiver, is known for being extremely robust and dependable. The C7 upper, originally only found on Canadian AR-15 models, is a blend of the M16A1 and M16A2, being essentially an M16A1 receiver with the "Burton bump" shell deflector found on the M16A2 receiver. This lefty friendly feature is now commonplace on modern forged uppers.

The barrel is 11.5 inches in length, with a 5.56x45mm chamber and 1-7 twist, making it a unique carry handle configuration with the tighter twist. The barrel features a chrome bore and chamber with a phosphate exterior finish. This light barrel makes the short upper extemely handy. The barrel is capped with an A1 flash hider. The included bolt carrier group is a standard mil-spec version, with a phosphate exterior and chrome interior carrier and gas key.
