The Faxon 5.56 Gunner Lightweight 9310 Bolt Carrier Complete is a top-quality upgrade for your AR-15 rifle. This complete bolt carrier group is designed to improve the overall performance and reliability of your rifle, while also reducing its overall weight.

The bolt carrier group is constructed from high-strength 9310 steel, which provides exceptional durability and resistance to wear and tear. The nitride finish adds an additional layer of protection against corrosion and other forms of damage, making this bolt carrier group ideal for use in harsh environments.

The Gunner Lightweight design of this bolt carrier group is optimized for improved performance and reliability. The reduced weight of the carrier and the enhanced cam path ensure smoother cycling, faster follow-up shots, and reduced recoil. The forward assist serrations are easy to grip, allowing you to quickly and confidently charge your rifle.

This bolt carrier group is compatible with all mil-spec AR-15 rifles, and the complete assembly ensures that installation is quick and easy. Whether you are a professional shooter or just someone who enjoys target shooting or hunting, the Faxon 5.56 Gunner Lightweight 9310 Bolt Carrier Complete is an excellent upgrade for your rifle. Its precision craftsmanship and attention to detail guarantee that it will perform flawlessly, shot after shot.

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:

  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

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.

    FAXON 5.56 GUNNER LIGHTWEIGHT 9310 BOLT CARRIER COMPLETE - NITRIDE

    If your looking to build a lightweight AR15 or AR Pistol this is a must. It’s lightweight, looks great and is tough. Performs well. As must have, and if you want a little flash try the Tin or PVD versions.

    The machining is flawless, the weight is right on as advertised.. An adjustable gas block let's you slow down bolt speeds, and it'll be a flatter shooter. I have 4 now, and I'll be back for more. Any plans for a lightweight AR10 carrier?

    My Faxon 5.56 Gunner Lightweight Bolt Carrier Group is much lighter than a regular bolt carrier group. I haven't gotten to use it much yet, but it should help with recoil and getting on target for a follow up shot. The finish is as slick as deer gu

    My Faxon 5.56 Gunner Lightweight Bolt Carrier Group is much lighter than a regular bolt carrier group. I haven't gotten to use it much yet, but it should help with recoil and getting back on target for a quick follow up shot. The finish is as slick as deer guts on a door knob! ;-) I love Faxon products!!!

    Light weight BCG

    Posted by CRAIG on Oct 10th 2018

    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

    Faxon Light weight BCG

    Posted by Michael Reynolds Sr on Oct 6th 2018

    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.
