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 in a Taper Mount. This design would be impossible to manufacture in a single CNC cut work piece. The welded on front cap features gas jet nozzles protected by a wire cutter shroud to focus concussive blast forward and away from the shooter and bystanders in the immediate vicinity. 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. For users seeking the lowest concussion muzzle device that can be used either stand alone or with a suppressor this is the unit for them.
Taper Mount Thread Protector is compatible with this muzzle device for added protection of thread mounts.

Griffin Armament® M-LOK compatible SR rails (Suppressor Ready) allow up to 1.5” outside diameter silencers to be mounted inside the octagonal M-LOK rail. This provides suppressor aficionados a sleek, and compact overall length to AR15 type firearms.
Design objectives of this rail were to provide a suppressor compatible rail, with increased rigidity and durability over similar weight and profile current market options. A custom extrusion provides significant internal reinforcements to reduce flex when loading the carbine on the rail. 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 such as practical shooting off barricades or when loading bipods for rapid follow up shots. Internal practical testing showed substantial reductions in POI shift with laser aimers versus competing "slim rails" that lacked this notable product feature.
The new SR rails features a close tolerance, heavy-duty, 7075 aluminum, T-6, type 3 hard coat anodized finish. The barrel nut can be easily installed to 35-85 ft/lbs using the included Griffin Armorers Wrench. The new slip fit clamp design is extremely user friendly and does not require any shims or special timing methods. The clamp geometry in the rear section of the rail is low profile and ergonomically pleasing even for long durations of extended carry at static security positions. Flat head T15 torx screws should be tightened to 25/in pounds. The included 45 degree picatinny QD sling swivel can be installed on the top picatinny rail to the desired position of the end user. M-LOK flats on each 45 degree surface allow for mounting of your favorite M-LOK accessories. A contiguous picatinny top rail ensures repeatable and accurate mounting for night vision and thermal systems.

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.
Features:
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.
Features:
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.

Specs:
A six position, mil-spec dimensioned receiver extension featuring 7 ports to allow excess gas, water, oil, and debris to leave the operating system, reducing pressure and associated danger to both host firearm and shooter, while enhancing reliability. Mil-spec hardcoat anodized. 7075-T6 is twice as strong as 6061-T6.
Features:
For users seeking a sleek, refined, anti-rotation QD end plate, the C2E Contour Connect End Plate is the perfect compliment to any AR15 or AR10 pattern rifle. Perfect for single point slings, where rapid strong to weakside transitions and rapid primary to secondary firearm transitions are desired.
Made from heat treated ordnance grade steel, and manganese phosphate finished for extreme durability. with a machined 8 position anti-rotation QD sling mount socket, the C2E follows the contours of the forged Mil-Spec lower perfectly, giving the lower receiver end plate a forged feel. A 45 degree chamfer with smooth corner radii gives the C2E a premium feel your rifle always should have had.

Specs:
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.
Features:
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.
Features:
Manufactured from high strength materials, the Griffin ECS™ is a compact, fully featured, no-compromise stock you can count on.
The ECS™ confronts design deficiencies in legacy systems. The current issued locking latch pin will bend and shear at the reduced diameter threaded shank, promoting stock failure- Griffin replaced it with a full diameter hardened stainless steel tool pin. The music wire spring is not a material recommended for outdoor use- the Griffin ECS™ uses 17-7 stainless steel springs which are outdoor use rated. The Griffin ECS™ also has water and debris evacuation ports compatible with the Griffin Maritime Receiver Extension, increasing system reliability and durability in extreme conditions. An anatomically angled, 60A Shore durometer rubber pad promotes straight line recoil, reducing muzzle climb associated with 90 degree angled systems. The rubber pad further provides non slip shouldering and comfortable recoil dampening, in weather conditions to -40F. An Ambidextrous, anti-rotation QD sling point is integrated into the stock, eliminating the capacity of the sling to wrap up when the firearm is stored or handled un-slung.
