LANTAC .308/7.62 E-BCG Full Auto Style Bolt Carrier Group - Nickel Boron

Out of stock

LANTAC E-BCG®, Enhanced Bolt Carrier Group. DPMS Gen 1 Pattern Only. AR10 Full Auto Style for increased mass and lock time.

  • Our DPMS Style 308 BCG 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.
  • This offers extreme lubricity with a friction coefficient of .02 and surface hardness of 82-85 Rockwell C.
  • The carriers patent pending design features unique shrouded and forward facing gas ports that have also been re-sized so that gas is vented differently to a standard carrier.
  • This results in a system that runs flatter with a smoother energy pulse.
  • 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 allows for a flatter more controlled reciprocation of the assembly.
  • All E-BCG's® feature 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 BCG's weight helps to increase lock time with smoother operation.
  • 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. 'Over Gassed' guns will suffer to a larger extent from this problem.
