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.

Ar-15 Lightweight 5.56 Bolt Carrier Complete Faxon Firearms.

$248.99 - $284.99
Faxon Firearms set out to create a bolt carrier group that could live up to the GUNNER name with no compromise in ...

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.

Complete bolt assembly is precision machined from an ultra-strong steel alloy to last up to 10 times longer than a standard carbon ...

Product Description

Complete bolt assembly is precision machined from an ultra-strong steel alloy to last up to 10 times longer than a standard carbon steel bolt, minimizing the risk of bolt failure during a critical engagement. SAE 9310 steel has a tough, ductile inner core highly resistant to stress fracturing, with a hard outer surface that resists galling and wear, to ensure a service life of up to 60,000 rounds. This is the same steel used in the transmission gears of Formula 1 race cars, so it’s ideal for high-impact, high-heat applications like sustained full-auto fire. Meticulously machined radiuses on all 90-degree corners on the locking lugs help distribute impact force evenly and further reduce risk of premature wear and cracking. Fully supported extractor face and precise extractor engagement further ensure smooth, reliable cycling.

Bolts are available individually, or in a completion group, which includes the bolt, firing pin, cam pin and firing pin retaining pin.  

Available caliber 223.

Product Description

For anyone using .308/7.62 AR-type rifles, it is common knowledge that many factory rounds exhibit excessive primer flow and/or ejector smear. At its core, this is a result of ammo development being done by manufacturers only for manual platforms without testing in semi-auto platforms. Some rifle manuals even record the maximum recommended load data beyond the functional range of these rifles. Unfortunately, these issues will persist until the manufacturers of ammunition realize that an AR platform requires a unique pressure curve to allow for both accuracy and reliability.

Manufactured to the exacting standards of our standard bolt offerings, the High Pressure EnhancedBolt™ design represents a giant leap forward in alleviating the problems traceable to over-pressured loads—namely primer flow, ejector smear, extraction issues, and ignition reliability. In combating these problems, this new bolt design opens up a much broader range of ammunition compatibility and load density in the AR .308/7.62 and other variants such as 6.5mm or 6mm calibers in this platform.

Complete bolt assembly is precision machined from an ultra-strong steel alloy to last up to 10 times longer than a standard carbon steel bolt, minimizing the risk of bolt failure during a critical engagement. SAE 9310 steel has a tough, ductile inner core highly resistant to stress fracturing, with a hard outer surface that resists galling and wear, to ensure a service life of up to 60,000 rounds.
