Brownells recently released the BRN-601 in OLIVE GREEN  which is a complete AR-15 upper receiver patterned after the original Colt Model 601 rifle.

Brownells states “Part of the Brownells Retro™ line of AR-15 components, our BRN-601 Complete Upper Receiver is a faithful recreation of upper on the original Colt Model 601 rifle. The 601 was the AR-15 originally issued to the U.S. Air Force that got the ball rolling toward the rifle’s adoption across all branches of the U.S. military. The Model 601 and the subsequent Model 602 are essentially identical to the later U.S. Army M16. The charging handle has been relocated from under the carry handle (on the early Armalite prototypes) to the rear of the receiver. Like the M16, the 601 lacks a forward assist. (The only difference between the 601 and 602 is a switch from 1-14″ rifling on the 601 to a faster 1-12″ twist on the 602.)”

FEATURES:

-Robust forged/machined 7075 T6 aluminum receiver
-Matte gray hardcoat anodized receiver – correct color for early rifles
-Chambered for modern 5.56x45mm NATO (.223 Remington compatible)
-20″ barrel with chrome-lined bore / chamber & 1-12″ twist rifling
-Rifle-length gas tube
