This drop-in upper will attach to virtually any standard AR-15 lower assembly. Comes complete with charging handle, bolt and bolt carrier assembly, it is ready to pin to a complete lower assembly without modification. This upper is a Flattop that features a four rail free float tube with rail covers, front and rear flip-up sights and Panther flash hider. Free float handguards are attached to the receiver only and do not contact any point on the barrel. This reduces the chance of accuracy-reducing pressure on the barrel.
