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, C-158 (Carpenter) 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.

Purchased this to use in an 18 inch ar15 PRS build and it has worked great. So far only have 700 rounds with no malfunctions running suppressed 100% of the time with both the Flow 556k and the Surefire RC2. I will be purchasing more in the future.
I love this bcg. The finish on it is so smooth. Nitriding is best I’ve seen even slightly topping my B&T nitrided parts. I have 5.5k suppressed rounds on my 14.5 MK1 and the bcg components are not wearing out. I don’t get it. Standing the BCG up it is nowhere near collapsing under its own weight. Gas rings perfectly in tact. I chalk it up to the smooth precision ground and nitrided internal of the carrier
Excellent rifle part. Bought two several years ago and have continued to purchase these BCGs. Well finished and well made, No problems or breakage after 1000s of rounds and hard use.
Have used your products in a past build and was very happy with the results. If it's not broke don't mess with a great product!
Excellent BCG both suppressed and unsuppressed. Cycles very well with zero issues even when caked in carbon build up. Full confidence in this BCG.
Own a Nickel Toolcraft. Griffin’s BCG is premium to that. Such a flawless output with a suppressed 300 blackout build. Cleans easily.
Top quality, American made, fast shipping, efficient, furthermore, this is the kind of small businesses we need.
Beautiful product, great price, made with pride. This Is the only BCG you should be running!
Oustanding product. I bought this BCG for my 300 blackout build and it has performed as expected, flawlessly. The mass is perfect, not too heavy, not to light for suppressed applications. Easy to clean.
Everything I buy from Griffin Armament exceeds my expectations. This BCG is no exception. Flawless workmanship. Beautiful detail and finishing. Most smooth operation! Thanks
