Lantac Nickel Boron E Bcg Dpms 308 Bolt Carrier Group

The LANTAC .308/7.62 E-BCG Full Auto Style Bolt Carrier Group in Nickel Boron is a DPMS Style 308 BCG precision machined from 8620 steel with a 9310 precision hard ground bolt, engineered to deliver smooth, reliable performance in both full auto and semi-auto configurations. Entirely coated with NiB, Electroless Nickel Boron, using the patented UCT EXO process, this carrier offers extreme lubricity with a friction coefficient around .02 and surface hardness in the 82-85 Rockwell C range, ensuring durable, low-drag cycling. The patent-pending design features unique shrouded and forward-facing gas ports that vent gas differently from standard carriers, promoting a flatter impulse, cooler operation, and cleaner cycling, with reduced upper receiver pressurization when running a suppressed barrel. A flared boss at the tail enhances carrier alignment within the buffer tube for flatter, more controlled reciprocation, while the forward porting and enlarged vents further optimize cycling dynamics. All E-BCGs include the CP-R360-H domed cam pin machined from 17-4PH stainless steel and hardened to H900 (approximately 45RC), delivering ultra-smooth head engagement to minimize wear inside the upper receiver. With a weight of 1 lb 2.1 oz, this carrier enhances lock time and smooth operation, making it a refined choice for shooters seeking precision, reliability, and cleaner, cooler performance in demanding DPMS-pattern .308/7.62 platforms.
