Colt Firearms LE6933EPRII PRO Complete Upper Features The Colt Firearms LE6933EPRII PRO is a complete upper receiver chambered in 5.56 NATO built around an 11.5 inch threaded barrel suited for compact maneuverable rifle configurations. Finished in matte black the upper provides a uniform durable finish that matches most AR-15 and M4 pattern lowers on the market so the completed rifle presents a consistent look from receiver to receiver. Being threaded the barrel accepts a wide range of muzzle devices and suppressors to suit a shooter s specific application whether that is flash reduction recoil control or sound suppression. Built to fit AR-15 and M4 pattern lower receivers the upper allows for straightforward assembly onto an existing stripped or complete lower without requiring any fitting or gunsmithing work. As a complete upper the LE6933EPRII PRO saves shooters the time and effort of individually sourcing a barrel bolt carrier group charging handle and handguard to build a compatible 5.56 upper from scratch. Colt s manufacturing reputation for military and law enforcement contracts carries over into this upper giving buyers a dependable duty-grade component built to the same standards that have made Colt a trusted name in AR-platform rifles for decades. The 11.5 inch barrel length strikes a balance between maneuverability and ballistic performance for short to medium range engagements making it a strong choice for close quarters work and vehicle-based scenarios where overall rifle length matters. The Colt Firearms LE6933EPRII PRO complete upper is for sale at GrabAGun for AR-15 owners who want a factory Colt build without assembling the upper themselves.
