This is an AR-pattern complete upper receiver assembly only, with no lower receiver present. The included bolt carrier group and charging handle make it a ready-to-pair upper assembly for a compatible AR-15 lower receiver.
The handguard is a free-float quad-rail style with numbered Picatinny rails, and the top rail runs continuously across the receiver and handguard for uninterrupted mounting space. The item also includes flip-up iron sights, with both front and rear present (brands not legible).
Markings on the receiver clearly identify it as an LWRC International M6A2 in 5.56mm, and it is marked "MADE IN THE U.S.A." These proof marks provide clear manufacturer, model, caliber, and country-of-origin identification.
Additional visible features include an ejection port cover and a slotted flash-hider-style muzzle device (exact make and model not identifiable).
