LANTAC E-BCG, Enhanced Bolt Carrier Group – AR15 5.56

M16 Full Auto Style for increased mass and lock time.
Our new BCG is precision machined from 8620 Steel with a shot peened bolt manufactured from Carpenter 158 or 9310 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.
