LANTAC E-BCG Nickel Boron Enhanced Bolt Carrier Group

Product Description

M16 Full Auto Style for increased mass and lock time.
Our new EBCG 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 patented and 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 gas key has been hard chrome lined for the best possible wear resistance.
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).
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.
