Description

Lantac Full Mass Full Auto Enhanced Bolt Carrier Group For AR Style 7.62 / .308 Rifles - Black Nitride

M16 full auto style for increased mass and lock time. Lantac’s BCG is precision machined from 8620 steel with a shot peened bolt manufactured from carpenter 158 and magnetically particle inspected. The entire carrier assembly is QPQ (quench polish quench) nitride coated black - a specialized type of nitrocarburizing case hardening that creates a very hard, smooth surface with increased corrosion resistance and low coefficient of friction.

The carriers patented design features unique shrouded and forward facing gas ports that have also been resized so that gas is vented differently to a standard carrier. This results in a system that runs flatter with a smoother energy pulse with a softer start to carrier movement.

In addition, the system also runs cooler and cleaner, there is also less pressurization of the upper receiver when running a suppressed barrel. The flared boss at the tail of the carrier enhances the BCG's position within the buffer tube at the time of cycling and makes it more consistent, resulting in smoother operation.

All critical dimensions are hard turned / ground after heat treat and the gas key has been hard chrome lined for the best possible wear resistance.

All E-BCG's feature the Lantac CP-R360-H patent pending domed head 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 BCG's 1 lb. 2.1 ounce weight helps to increase lock time and smoother operation.

Gas keys are fitted with gasket sealer and are properly staked at four points and only grade 8 fasteners are used in assembly. The E-BCG's forward porting and unique shape assist in reducing pressurization inside the upper receiver that can be caused by short barrel rifles running suppressors. However, it should be noted that the E-BCG is not a complete solution for this issue and all rifles are different. Guns that are over gassed will suffer to a larger extent from this problem.
