This is a pretty cool old school colt. It is C marcked with cero forge government markings. The 14.5" barrel is M4 cut with the appropriate colt markings and code. The muzzle device is a surefire suppressor mount timed with shims. The barrel has a 2009 manufacture date and is not P&W. This upper receiver would be a great addition for a cloner looking to rebarrel for an SPR or just run it as an M4 clone. No m4 feed ramps, but functions well as is. No BCG or CH included.
