Mfr:ADAMS ARMS
Status:In Stock

Complete Upper, Ready To Install To Make A Reliable, Clean-Running Piston Carbine

Mounts on a standard, mil-spec AR-15 lower receiver to produce a reliable, positive-cycling gas piston gun
Piston system gives smoother feeding, easier maintenance, less violent cycling, and reduced felt recoil
Doesn’t vent hot gases and burned powder into receiver, so the gun runs cooler, with reduced fouling and wear on the action
Gas block can be adjusted for three operating modes: normal fire, firing with a suppressor attached, or a single round fired without cycling
All models have a Picatinny rail on top of the gas block to accept a variety of clamp-on front sights
Carbine model offers a Parkerized 16" barrel and an M4-style carbine plastic handguard
Pistol features a 7½" barrel and two-piece handguard with four, 3" Picatinny rails
Pistol Extended Rail features a 7½" barrel and an extended handguard with 6" side rails, a 5¾" bottom rail, and a 4¼" top rail that forms a continuous 12" rail with the receiver flattop and gas block; QD swivel attachment points
Forged receiver features M4 feed ramp cuts and a 13-slot Picatinny-cut flattop rail
Chrome-lined barrels are chambered for 5.56mm NATO and include an A2 flash hider
Midlength - 16" barrel, M4-style handguards, and midlength gas system
All NFA rules apply
