    Item Code: #453217907

    Availability: In stock

    Ready To Install To Make A Reliable, Clean Running Piston Carbine Or Pistol Complete Tactical Elite upper receiver assembly comes ready to install on mil-spec lower receiver to produce a reliable, positive-cycling gas piston gun. Adams Arms’ proven piston system doesn’t vent hot gases and burned powder into the bolt carrier and receiver, so the gun runs cooler, with less fouling and wear on the action, and easier maintenance.

The receiver is forged from 6061 T6 aluminum and features M4 feed ramp cuts and a 13-slot Picatinny-cut flattop rail. The adjustable gas block allows three levels of gas release: normal fire, firing with a suppressor attached, or a single round fired without cycling. Picatinny rail on top of gas block accepts a variety of clamp-on tactical sights. All models have chrome-lined barrels chambered for 5.56mm NATO, with an A2 flash hider and a black Melonite® finish for superb wear resistance and up to 60% more corrosion resistance than traditional phosphate coating.  Pistol - 7½" barrel and two-piece, machined aluminum handguard with four, 3" Picatinny rails. Pistol Extended Rail - 7½" barrel and an extended, aluminum 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. Mid-Length - 16" barrel with extended 12" handguard.  Side rails include sockets for QD sling swivels. All NFA rules apply.

    $29.99

    Item Code: #453217907

    Availability: In stock

    Precision-Machined To Upgrade Your Existing Hammer & Trigger Pins; Available Standard & OversizedRedesigned hammer pin and anti-rotation links provide the strongest possible system to eliminate pin rotation, and will withstand the additional force exerted by 9mm conversions and suppressed .223 upper receivers. Helps prevent wear to receiver holes, which is especially important for increasingly-valuable M16 and pre-ban receivers. Notched hammer pin locks into slots in the anti-rotation links; trigger is secured with locking screws, and includes lube ports so adequate lubrication reaches the trigger. Anti-rotation links fit on the outside of the receiver to prevent all movement. Pins are CNC-machined, centerless ground for uniformity and heat treated for durability. Available in Standard .154", Oversized .155", and .170" for larger receivers. Oversized Pins help improve accuracy and trigger control by tightening up any trigger slack that may exist in worn or new receivers. Standard-sized pins drop-in and require no modification to the receiver; oversized pins require the use of the 3.95mm Reamer (available separately).

  • AR-15/M16 5.56 ENHANCED BOLT COMPLETION GROUP J P ENTERPRISES
    $137.99

    Item Code: #453217907

    Availability: In stock

    Complete bolt assembly is precision machined from an ultra-strong steel alloy to last up to 10 times longer than a standard carbon steel bolt, minimizing the risk of bolt failure during a critical engagement. SAE 9310 steel has a tough, ductile inner core highly resistant to stress fracturing, with a hard outer surface that resists galling and wear, to ensure a service life of up to 60,000 rounds. This is the same steel used in the transmission gears of Formula 1 race cars, so it’s ideal for high-impact, high-heat applications like sustained full-auto fire. Meticulously machined radiuses on all 90-degree corners on the locking lugs help distribute impact force evenly and further reduce risk of premature wear and cracking. Fully supported extractor face and precise extractor engagement further ensure smooth, reliable cycling. Bolts are available individually, or in a completion group, which includes the bolt, firing pin, cam pin and firing pin retaining pin.   Available caliber 223.
