Faxon Superfinished 6.5 Grendel Type II Bolt Carrier Group | Black Nitride

The Faxon Superfinished Grendel Type II bolt carrier group is engineered for shooters who demand exceptional reliability and smoothness from their AR-15 platform. Designed specifically for 6.5 Grendel and 6mm ARC chamberings, this BCG features a Type II bolt face with a .136-inch depth for proper headspacing and compatibility with precision barrels. It is a purpose-built heart for a serious mid-caliber build.

What the Faxon Superfinished Grendel Type II BCG is and who it is for

This bolt carrier group is for builders running 6.5 Grendel or 6mm ARC who want a BCG matched precisely to those cartridges. The Type II bolt face and .136-inch depth are what set it apart from a standard 5.56 bolt, ensuring correct headspacing on Grendel and ARC barrels. If you are chasing accuracy and reliability from a mid-caliber AR, this is the correct BCG for the job.

Precision shooters and dedicated Grendel and ARC builders will value the exact fitment. The Faxon Superfinished Grendel Type II BCG removes the compatibility guesswork from a specialized build.

Key features

• Purpose-built for 6.5 Grendel and 6mm ARC chamberings
• Type II bolt face with .136-inch depth for proper headspacing
• Faxon Superfinish process for near-mirror smoothness on critical surfaces
• Advanced black nitride finish for corrosion resistance and reduced friction
• Machined from premium materials for long-term durability

Specifications and materials

The Faxon Superfinished Grendel Type II BCG is machined from premium materials and treated with Faxon’s advanced black nitride finish to ensure long-lasting corrosion resistance, reduced friction, and enhanced wear protection. That finish is a workhorse coating that keeps the group running clean and cycling smoothly under real conditions. It is built for the long haul.

The standout feature is Faxon’s proprietary Superfinish process, which polishes every critical surface of the bolt carrier group to near-mirror smoothness. This reduces friction, eases cleaning, and promotes consistent cycling even under high round counts. The result is a BCG that operates smoothly and predictably, exactly what a precision build needs.

Smooth cycling is more than a luxury on a precision rifle; it contributes to the consistency and reliability that show up on paper. Faxon’s Superfinish process polishes the group’s critical surfaces to a near-mirror smoothness that reduces friction and helps the action run cleanly even as fouling accumulates. Combined with a durable black nitride coating for corrosion resistance and wear protection, it produces a group that operates predictably through long range sessions. For a 6.5 Grendel or 6mm ARC build chasing accuracy, that consistency is exactly what you want at the heart of the rifle.

Installation, care, and compatibility

Installation is simple for a complete BCG. Pair it with a 6.5 Grendel or 6mm ARC upper, insert it along with your charging handle, and confirm smooth travel and lockup. Because it ships as a complete group with the correct Type II bolt, there is no headspacing guesswork on a matched barrel. Lubricate it properly before its first range trip.

Care is easy thanks to the Superfinish and nitride coating, which shed carbon and wipe clean with little effort. Keep it lubed and inspect the bolt and gas rings periodically. The Faxon Superfinished Grendel Type II BCG drops into standard AR-15 uppers built for Grendel or ARC, so browse our parts and upgrades catalog for the charging handles and internals to complete it. Trust Faxon to deliver a BCG worthy of a precision rifle.

Caliber-correct components are non-negotiable on a mid-caliber AR, and the bolt is where that matters most. The Type II face and .136-inch depth are specific to the 6.5 Grendel and 6mm ARC case head, and using the wrong bolt leads to headspacing problems and unreliable extraction. Buying a group built for these cartridges removes that risk entirely.

The Superfinish process is more than a marketing term. Polishing the carrier and bolt surfaces to a near-mirror finish genuinely reduces friction, which smooths cycling, eases cleaning, and helps the action run reliably even as fouling accumulates. Layered under a durable black nitride coating, it produces a bolt group ready for the demands of a precision build.

For a smooth, correctly headspaced heart to your 6.5 Grendel or 6mm ARC build, the Faxon Superfinished Grendel Type II BCG delivers. Ships direct to your door, no FFL required.
