LANTAC ENHANCED BOLT CARRIER GROUP 762
The LANTAC Enhanced 7.62 Bolt Carrier Group is a precision-built BCG for AR-10 rifles that prioritizes smooth operation, reduced wear, and suppressor-friendly performance. Machined from 8620 steel with a 9310 hard-ground bolt, this DPMS-pattern carrier gets LanTac's proprietary UCT EXO electroless nickel-boron coating—a step above standard NiB finishes. The result is a friction coefficient of .02 and surface hardness of 82–85 Rockwell C, meaning the group cycles with minimal resistance and cleans up easier after range time or hunting.
What sets this BCG apart is its patent-pending gas porting design. The shrouded, forward-facing gas ports are sized and angled differently than a conventional carrier, directing the impulse pulse more smoothly down the system. That translates to flatter recoil, cooler running temperatures, and reduced fouling—especially useful if you're running a short-barrel or suppressed setup. The flared boss at the tail of the carrier keeps the group's movement controlled and consistent within the buffer tube, reinforcing that predictable cycling. Every critical dimension is hard-turned or ground after heat treat for consistency, and the included CP-R360-H domed cam pin (17-4PH stainless, hardened to H900) is engineered to reduce upper-receiver wear over time.
Built to mil-spec throughout, with a four-point staked gas key and grade-8 fasteners, this is a workhorse BCG made in the USA. At just over a pound, it carries enough mass to improve lock time without throwing off your rifle's balance. Whether you're a serious long-range hunter, a suppressor enthusiast, or someone who simply wants a carrier that runs clean and runs cool, this LanTac group delivers.

Frequently Asked Questions
Will this BCG work in my AR-10?
Yes, provided your rifle uses a DPMS-pattern carrier (the most common AR-10 standard). Always verify your specific platform's compatibility before purchasing. If you're unsure, contact our team.
Does this BCG reduce issues with suppressed or short-barrel AR-10s?
The forward-facing, shrouded gas ports and unique carrier shape help reduce upper-receiver pressurization common in suppressed and short-barrel rifles. However, this BCG is not a complete solution for over-gassed guns; results vary depending on your specific rifle, barrel length, and suppressor combination.
What comes in the box?
The BCG includes the carrier, 9310 bolt, CP-R360-H domed cam pin, mil-spec gas rings, and mil-spec staked gas key. All fasteners are included.
How does the UCT EXO coating compare to standard nickel-boron?
LanTac's proprietary UCT EXO coating achieves a lower friction coefficient (.02) and higher surface hardness (82–85 RC) than conventional NiB finishes, resulting in smoother cycling, easier cleaning, and reduced wear over time.
