Faxon Releases GUNNER MSR Bolt Carrier Groups

(Cincinnati, OH) – (ArmsVault.com) – Faxon Firearms, incessant innovators in the firearms industry, is pleased to announce the release and shipment to dealers of its GUNNER bolt carrier groups.

Keeping with the GUNNER tradition, the new bolt carrier groups minimize weight while maximizing utility. The stripped carrier with key weighs in at 6.4 ounces, maintaining forward assist serrations and full-auto compatibility for duty use and new “active” trigger systems.

MIL-SPEC or improved materials are used through the complete group. The bolt carrier is 8620, fully heat-treated. The GUNNER’s bolt is constructed of 9310 tool steel, which is stronger than Carpenter 158 and the extractor is S7 tool steel. Both the bolt and extractor are heat-treated, shot peened, and coated. All components are QPQ Salt Bath Nitride finished for improved surface hardness, lubricity, corrosion resistance, and ease of cleaning.

“Faxon worked hard to create a bolt carrier group that could live up to the GUNNER name. The BCG is lightweight; keeping all the functionality needed for competition and high-speed rifle builds,” said Nathanial Schueth, Director of Operations, Sales & Marketing. “Further, we were able to accomplish this while exceeding MIL-SPEC using improved materials and the QPQ Salt Bath Nitride finish.”

The GUNNER bolt carrier groups, both stripped and complete series, are now shipping from Faxon Firearms and through its Dealer network. MSRP for the GUNNER complete bolt carrier group is $249. Stripped carriers with key installed have an MSRP of $199.

For the GUNNER’s launch, Faxon is proud to partner with is Rainier Arms, offering the first limited run for $199.
