Faxon 5.56 Gunner Lightweight Bolt Carrier Group, Nitrided
When looking at lightweight bolt carrier groups, we were unsatisfied with what the market had to offer. Seeing a capability gap, we set out to create a bolt carrier group that could live up to the Gunner name with no compromise in strength or function. We set specifications that would allow no compromise:
- Lightest Weight Possible (8.5 Ounces Complete)
- MIL-SPEC Materials & Finishes or Better!
- Forward Assist Serrations
- Compatible with Dust Covers
- Maintains Full-Auto Trip Sear for full-auto and the new multi-stage trigger functionality
Matching our barrels, we selected 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 Nitride process seals components against corrosion while making them fantastically wear resistant.
Improvements include using 9310 tool steel for the bolt, 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.
Faxon recommends the use of an adjustable gas block with our Gunner lightweight BCG for proper function.

This thing is sweet. By far the best BCG ive ever handled.
I bought this to try out in a new upper build and to offer my customers should there be interest and good results. I am very impressed not only with form but function. No feed issues, all rounds ejected properly and little if barley felt recoil
I have purchased several of these. There are lighter ones out there (aluminum, tiyanium) but these are made from steel, so I like them better. They will stand up to heavier use. Have never had any issues. They also have the serrations for a forward assist if needed. Wish they would just sell the carrier w/o bolt or add bolts for other calibers (6.8, 6.5 Grendel).
This was a great upgrade to my 3 gun rifle. After a few thousand rounds of with a cheaper lightweight bcg I started to have slam fires. I’ve run 14.5 and 16 inch gunner barrels in my rifle so I knew going with faxon I’d be getting a quality bcg. My rifle has been running flawlessly the last few matches. I’ve been very happy with all my purchases from Faxon.
Amazing quality. I have two light BCG evo Voodoo Adam's Arms high quality 5.56 rifles, and their bolts are an ounce heavier and are piston driven. This bolt is "worth it's weight " to use in a fine build. With a Faxon Barrel and upper receiver you can't go wrong. Very high quality product !
I have the Faxon Gunner BCG in a precision AR build. The low mass of the BCG, combined with an adjustable gas system and suppressor, make recoil minimal. Its very easy to stay on target for rapid follow up shots. I have not experienced any sort of failure with this AR-15 so far. The BCG is very well designed and machined. Faxon has removed material in just about every imaginable area to save weight while maintaining function. The nitride coating makes cleaning very easy. I would definitely buy another one if I was assembling a new precision AR.
