Introducing the LANTAC E-BCG™, Enhanced Bolt Carrier Group. 

  • M16 Full Auto Style for increased mass and lock time.
  • The 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 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 lock position within the upper and makes it more consistent, resulting in an accuracy improvement.
  • All critical dimensions are hard turned / ground after heat treat and the bore of the carrier and gas key have been hard chrome lined for the best possible wear resistance.
  • All E-BCG's feature the LANTAC CP-R360™ 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 11.7oz weight helps to increase lock time and smoother operation.
  • Gas keys 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. 'Over Gassed' guns will suffer to a larger extent from this problem.

    LANTAC BGC 223 Enhanced

    I have purchased 4 of these units and run them on my short barreled ARs. I like the extra weight for controlling the recoil, yes it helps. You will not be disappointed with this in your rifle.
