Colt Firearms LE6920EPRII Complete Upper Features The Colt Firearms LE6920EPRII Complete Upper pairs a 16.1 barrel chambered in 5.56 NATO with a complete upper receiver assembly giving shooters a drop in path to a new configuration on their existing AR-15 or M4 pattern lower. Because the upper arrives complete there is no need to source and assemble individual components saving time and reducing the chance of fitment issues during a build. The matte black anodized finish protects the receiver and barrel from corrosion and wear while keeping a low visual profile that matches most factory and aftermarket lowers. Fitting standard AR-15 and M4 lower receivers means this upper works with the vast majority of rifles already in a shooter s collection. Swapping to this upper lets an existing lower take on a fresh barrel length and configuration without the cost of acquiring an entirely new rifle. The 16.1 barrel length strikes a practical balance between maneuverability and ballistic performance for a 5.56 platform suiting range use home defense and general purpose shooting alike. Colt s reputation for military and law enforcement grade manufacturing standards carries through to this upper built to the same specifications the company is known for.
