LANTAC M-SPEC BCG 762 NITRIDE BLK

LANTAC M-SPEC BCG 762 NITRIDE BLK – MIL-SPEC STRENGTH MEETS PREMIUM FINISH

The LANTAC M-SPEC BCG 762 NITRIDE BLK is designed to deliver professional-grade performance in AR-10/LR-308 platforms. Featuring MIL-SPEC materials and a black nitride finish, this bolt carrier group offers a rugged, reliable upgrade for rifles chambered in .308 Winchester, 7.62 NATO, and compatible calibers.

BUILT FOR DPMS PATTERN AR-10 RIFLES

Engineered for DPMS Gen 1 / LR-308 pattern upper receivers, this BCG is drop-in ready for most large-frame AR rifles. Whether you're running a precision .308 setup or a battle-ready 7.62 rifle, the LANTAC M-SPEC BCG is ready for hard use and high round counts.

8620 STEEL CARRIER WITH FULL-AUTO PROFILE

The carrier is machined from 8620 steel, heat-treated, and finished in black nitride for maximum surface hardness and corrosion resistance. The full-auto profile ensures reliable cycling and smoother recoil management with higher-pressure rounds.

MPI-TESTED 9310 BOLT FOR MAXIMUM DURABILITY

The bolt is made from 9310 steel, a material known for being stronger than standard Carpenter 158. It is Magnetic Particle Inspected (MPI) and shot-peened for enhanced durability under stress, making it ideal for .308 and 7.62x51mm rifles.

BLACK NITRIDE FINISH FOR SMOOTHER FUNCTION

The nitride finish offers a slick, low-friction surface that reduces carbon buildup, improves wear resistance, and makes cleaning easier—ideal for suppressed or high-volume shooting.
