Why a BCG from
Griffin Armament? The simple answer is that these BCG's are the best
we've seen 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 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.
