Mfg Part#



The Lantac BCG is precision machined from 8620 steel with a shot peened bolt manufactured from Carpenter 158 and Magnetically Particle Inspected. All E-BCG's feature the LANTAC CP-R360 patent pending domed head cam pin that is machined from 17-4PH Stainless Steel and hardened to H900 condition (45RC approx).

  • Entire carrier assembly is QPQ (Quench Polish Quench) Nitride coated Black
  • Features unique shrouded and forward facing gas ports that have also been resized so that gas is vented differently to a standard carrier
  • System runs flatter with a smoother energy pulse with a softer start to carrier movement
  • Runs cooler and cleaner, there is also less pressurization of the upper receiver when running a suppressed barrel.
  • Flared boss at the tail of 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 gas key has been hard chrome lined for the best possible wear resistance
  • Gas keys are fitted with gasket sealer & are properly staked at four points and only grade 8 fasteners are used in assembly
  • Made in the USA
  • Lifetime Warranty

NOTE : 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.
