The XM177E2 Commando Returns. This Retro Classic Carbine is built to the Original Colt Model 629 specifications from the 1960s. The 11.5" Barrel has an extended flash hider designed to replicate the original moderator that was so iconic for this model. We've cut no corners, reproducing the original Vinyl-Acetate coated Aluminum Buttstock and reproducing the US Property Marked rollmarks. This is a true collectible that's as comfortable on the range as it will be in an enthusiast's display.
