Lot 401:
Colt M4 5.56 NATO Parkerized Barrel Assembly with 14.5 Inch Barrel
Description
This lot features a detached M4-profile barrel assembly chambered in 5.56 NATO, specifically designed for AR-15 and M16 style platforms. The 14.5 inch barrel is manufactured from 4150 chrome moly vanadium steel with a 1:7 inches twist rate and a durable Parkerized matte black finish. It features the signature M4 grenade launcher cutout forward of the gas block. Key components include a birdcage-style flash hider secured with a crush washer, a fixed A2-style front sight base with bayonet lug and bottom-mounted sling swivel, a handguard retainer cap, and a complete delta ring assembly. Verified markings on the barrel exterior include 5.56 NATO 1/7, while the front sight base is stamped with a C and a 2 within a circle, confirming Colt manufacture. The breech end features a barrel extension with M4-style feed ramps.
Condition report:
The barrel assembly is in excellent overall condition, retaining nearly all of its original Parkerized finish with only minor surface scuffs and handling marks. The bore is bright with sharp, well-defined rifling and shows no evidence of significant use or corrosion. The gas block and front sight assembly are securely pinned, and the mechanical components of the delta ring function correctly.
