7075 T6 Forged Mil-Spec Upper and Lower Receiver with Mil-Spec Fire Control Pocket
Billet machined from 2 pieces of 17-4 Stainless steel, this device is precision TIG welded together to provide the largest possible internal expansion chamber which reduces concussion as effectively as possible. This design would be impossible to manufacture in a single CNC cut work piece. The flash hider front cap was derived and applied from the high performance RECCE suppressor flash hider front caps while adding a thick erosion resistant face to ensure extremely long service life. CNC machining this device in two pieces is more expensive and time consuming than a single piece device for both machine time and human handling however no corners were cut to produce the optimal design. Blending lower pressure concussion and flash with reduced recoil and muzzle movement has been made possible for Taper Mount Suppressor users with the Taper Mount Tactical Compensator.
Taper Mount Thread Protector is compatible with this muzzle device for added protection of thread mounts.

Griffin Armament® M-LOK compatible Low-Pro rails are a slim, low profile, ultralight, yet rigid M-LOK rail. Design objectives of this rail were to provide a slim, ultralight rail, with increased rigidity over similar weight and profile current market options. A custom extrusion provides significant internal reinforcement to reduce flex when gripping the carbine firmly in the shoulder pocket. Understanding the importance of low light targeting, these reinforcements provide rigid mounting for IR laser aimers ensuring minimal POI shift when torque is applied to fore-grip type accessories, or when loads are applied to the rail (shooting off barricades, loaded bipods etc). Internal testing showed 70% less POI shift with laser aimers versus competing "slim rails". Carefully positioned slots in the rail allow for rapid cooling when running the carbine fast while maintaining rigidity.
The Low-Pro rail features a close tolerance, heavy-duty, 17-4 stainless steel H900 heat treated barrel nut, which can be installed with the included Griffin GI Armorers Wrench. The rail is very user friendly to install. The slip fitted clamp design doesn't requiring any shims or special timing methods. The clamp boss in the rear section of the rail is low profile and ergonomically pleasing for relaxed posture carry at static positions. Flat head T15 torx screws should be tightened to 25/in pounds. The barrel nut should be tightened to ~55ft/lbs. The included 45 degree Picatinny QD Swivel Mount is installed on the top picatinny rail to the desired position of the end user.
M-LOK slots at the 3, 6, and 9 o'clock positions allow for mounting of your favorite M-LOK accessories.

Why a BCG from Griffin Armament? The simple answer is that these BCG's are the best we've used in our ten years of military service and over a decade of industry involvement. When you look at a top shelf product you can see its quality. These are the best mil spec pattern there are.
The Griffin BCG combines an 8620 carrier, 9310 Bolt, 4340 cam pin and extractor. All the proper heat treats, the correct shot peen, and the often neglected post heat treated grind are present. In a market filled with cast component BCG's, all components are billet machined and all surfaces receive a finish pass in machining for improved surface smoothness. There are varying degrees of quality in Melonite QPQ finishes. These BCG's went to 4 finishing houses for selection of the finish provider, cost not being a consideration. The result is a deep black finish with remarkable lubricity. These are assembled to the current military technical data package with permatex'd and properly staked carrier keys. They also feature the current 15,000 round extractor spring design and a Crane O ring for reliable extraction in extreme conditions. We ran these thousands of rounds in multiple manufacturers rifles throughout the T&E phase without a single malfunction. From first sight through months of use to the final product launch we have remained excited to bring this BCG to market. This is the only BCG that has ever excited us and that is why we have chosen to offer it to the people we care about, our customers.
Many Metallurgists consider AISI 9310 alloy steel as an acceptable bolt material and substitute for Carpenter 158 (Carpenters brand name AISI P6 Spec mold steel). However, for the M4 purists we offer our BCG with the optional Carpenter 158 bolt made to current Mil-Spec including phosphate rather than Melonite treatment which comes with the 9310 bolt.

The SN-ACH™ (Suppressor Normalized Ambidextrous Charging Handle) is a patented, modernized, feature filled charging handle that will satisfy any AR15 user. The SN-ACH™ features a gas check groove and a suppressor gas vent that reduces gas in the face of the shooter when using a suppressor. The bolt carrier engaging hook features durable reinforced geometry for 30% increase in strength over milspec handles and approximately 3x as strong as inferior 6061 handles which routinely break under hard use. Fitment bearing surfaces on the handle mating ensures reduced wobble fitment with the Ar15 upper reciever. The handle is made from 7075-T6 aluminum and hard coated for optimal wear resistance.
- 6061-T6, Type 3 hardcoat anodized
- Fits all standard AR15/M4/M16 family firearms
The AR suppressor optimized buffer is a spring loaded, staggered impact, urethane buffered design. The reciprocal and non-reciprocal weights are similar to the A2 rifle length buffer. In conjunction with shock dampening brass weights, the AR-SOB offers increased system dwell time, reduced bolt speed, and enhanced chambering reliability. Through integration of a shorter platter of CNC machined weights and a telescoping buffer head, the AR-SOB has more controlled motion tolerances, allowing precisely controlled timing and forced sequential impact of buffer weights interacting with the rifles operating system. The AR-SOB weighs 4.9 ounces, and can be used in suppressed 5.56mm rifles as a replacement for the M4 carbine series buffers, and also in 308 carbines as a replacement for H2 and H3 buffers when used in conjunction with the AR10 mil-spec CAR receiver extension and AR10 CAR action spring.
- Brass weights and heat treated 17-4 Stainless Steel construction
- Staggered impact hybrid buffer design
- Rifle buffer function in a CAR system size for unsurpassed reliability

The Griffin Enhanced Trigger Guard offers a more comfortable guard than mil spec, while filling in the rear void in the receiver trigger guard boss that commonly irritates the middle finger.
A bit more room accommodates lightweight gloves better than the milspec. A spartan upgrade to the Ar15 but none the less a quality part.
Built around a heat treated ordnance grade steel central selector hub, two black nitride 17-4 selector paddles can be configured to the users needs whether the user is right or left handed. The hub incorporates an optional screw for trigger match style overtravel adjustment of standard AR-15 or M4/M-16 triggers, enhancing the human interfaced accuracy of the host firearm (enhanced shoot-ability). Overtravel adjustment reduces the time that the applied trigger pull weight is removed from the rifle during firing after the trigger break and prior to reaching the limit of travel. Reducing this time of lost equilibrium, reduces the wobble zone created by the removal of weight at the moment of break.
Utilizing the traditional 90 degree pattern, this selector requires the manipulation you are familiar with and have come to expect in the AR-15 / AR10 family of firearms.
- heat treated 17-4 ordnance grade steel selector paddles and central selector hub
- Black nitrided paddles
- Paddles can be reconfigured for left or right handed users
- Paddles match the stylistic geometry of the Griffin Armament Suppressor Normalized Ambidextrous Configurable Handle (SN-ACH™)
Typical production AR-15 pins are ~.245" diameter and flat on the ends. They operate in .250 pin holes, and items used to push the pins occasionally slide off and can scratch your lower receiver.
This pin set is ~.248" diameter, allowing you to improve your upper to lower receiver fit, and features early Armalite / early Colt style dimples to assist in location of bullet tips or tools used to push the pins. The tool locating dimples reduce the likelihood of scratching your lower and add a nice feature to ease dis-assembly.
The A3 provides excellent comfort and ergonomic feel, without loss of positive weapon retention or ease of safety selector manipulation. The Griffin A3 is compatible with the USGI trigger guard's winter guard function for gloved or mitten use. Textured to match the Griffin Armament Rail-Shield M-Lok furniture kit.
