Product Description

Complete, mil-spec assembly with bolt, bolt carrier, and firing pin ready to drop into the rifle or carbine upper of your choice.  Each bolt assembly is high pressure tested and magnetic particle inspection tested to ensure it’s free from imperfections that can lead to premature failures. Properly staked gas key prevents gas leakage that can lead to short stroking. M16-style carrier on the black phosphate model has full-length shroud for tripping auto sear, so this carrier may be installed on full-auto law enforcement and military rifles.  Carrier and gas key are chrome lined for smooth cycling and resistance to wear from hot combustion gases for years of dependable service.

SPECS: Steel, black parkerized finish. Fits mil-spec semi-auto and full-auto AR-15/M16 upper receiver chambered for .223/5.56mm.

Product Description

Faxon Firearms set out to create a bolt carrier group that could live up to the GUNNER name with no compromise in strength or function. They set specifications that would allow no compromise:

1. Lightest Weight Possible (8.5 Ounces Complete)
2. MIL-SPEC Materials & Finishes or Better!
3. Forward Assist Serrations
4. Compatible with Dust Covers
5. Maintains Full-Auto Trip Sear for full-auto and the new multi-stage trigger functionality
6. Looks Amazing

Matching their barrels, they selected the QPQ method of Salt Bath Nitride for all the carriers’ components. By coating all parts, the carrier's natural slickness is increased markedly requiring less gas and pressure to operate. Further, the QPQ SBN process seals components against corrosion while making them fantastically wear resistant.

Improvements include using 9310 tool steel for the bolt, which is stronger and nitriding the assembly to increase surface hardness, decrease resistance, and have superior corrosion resistance compared to typical chrome and phosphasted bolt carrier groups. All bolts are fully MPI tested to ensure the material is sound and without defects. Bolt lugs are chamfered 45 degrees to ensure reliable action for even the highest pressure hand loads and fast lightweight actions.

Faxon Bolt Carrier Groups are Superfinished to reduce friction, increase smoothness of operation, and reduce fouling. Further, they are full-Auto rated and maintain the trip for full-auto fire control groups and new multi-stage trigger systems. Gas keys use grade 8 fasteners and are fully staked for a lifetime of service.

As a testament of our confidence, the carriers are all laser-engraved with the Faxon Shield after passing all Quality inspections.

Product Description

Precision-machined, stainless bolt-and-carrier group features JP’s enhanced bolt made of high-grade 9310 steel for a significantly longer life expectancy than standard mil-spec bolts. Set is available with choice of JPBC-2A Low Mass carriers that reduce felt recoil and increase bolt speeds slightly for enhanced rapid fire handling, or the standard JPBC-2A Full Mass carriers that replicates the normal carrier weight and is preferred for duty rifles or any time absolute reliability is required. Standard weight carrier features a 100% increase in bearing surface for smoother cycling and reduced wear on the inside of the receiver. Both the JPBC-2A carriers feature JP’s super-hard QPQ finish for maximum wear resistance and minimal friction. Extractor, firing pin, and all other components are included.
