Lantac USA Enhanced Bolt Carrier Group 308 Nickel Boron AR-10 - LA00300

Lantac Enhanced Bolt Carrier Group

The Lantac E-BCG with 8620 steel construction; electroless nickel boron finish; unique shape; forward porting; 9310 bolt; carrier; balanced flared boss; CP-R360-H domed cam pin; grade 9 hardened fasteners; ultra-smooth head; Mil-Spec staked gas rings & keys; and 2.1 oz weight.

This DPMS Style 308 Lantac Enhanced BCG for sale at Mister Guns is precision machined from 8620 steel with a 9310 precision hard ground bolt. The entire carrier assembly is NiB, Electroless Nickel Boron coated with the patented, advanced UCT EXO process, unlike standard NiB coatings; and this offers extreme lubricity with a friction coefficient of .02 and surface hardness of 82-85 Rockwell C.

The patent pending design of the Lantac E BCG features unique shrouded and forward facing gas ports that have also been resized so that gas is vented differently to a standard carrier. The result is a system that runs flatter with a smoother energy pulse; the system also runs cooler and cleaner, and there is less pressurization of the upper receiver when running a suppressed barrel.

To allow for a flatter more controlled reciprocation of the assembly, the flared boss at the tail of the carrier enhances the BCG's position within the buffer tube at the time of cycling. All critical dimensions are hard turned / ground after heat treatment.

Like all E-BCG's, this Lantac Bolt Carrier Group features the LANTAC CP-R360-H™ patent pending domed cam pin that is machined from 17-4PH Stainless Steel and hardened to H900 condition (45RC approx). The ultra-smooth head reduces wear within the upper receiver; the weight of the BCG helps to increase lock time with smoother operation; and gas keys are properly staked at four points with only grade 8 fasteners used in assembly.

The forward porting and unique shape of the Lantac EBCG assist in reducing pressurization inside the upper receiver that can be caused by short barrel rifles running suppressors. However, note that this product is not a complete solution for this issue and all rifles are different. 'Over Gassed' guns will suffer to a larger extent from this problem.
