Manufacturer details
M16 Full Auto Style for increased mass and lock time. Our 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 QPQ (Quench Polish Quench) Nitride coated Black this is a specialized type of Nitrocarbrising Case Hardening that creates a very hard smooth surface with increased corrosion resistance and low coefficient of friction.
The carriers patented and patent pending design features unique shrouded and forward facing gas ports that have also been resized so that gas is vented differently to a standard carrier.
This results in a system that runs flatter with a smoother energy pulse with a softer start to carrier movement.
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.
