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 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.

The 2A Armament™ AR-15 Steel takedown pin set features the same classic through drilled design as our popular Titanium takedown pins but with a black oxide finish to accommodate for personal preference. These pins are made from U.S.A. sourced 4140 steel and weigh in at 0.38 oz total for both pins combined. The 2A Armament takedown pins are aesthetically pleasing on both our BALIOS and BALIOS-LITE line of receiver sets, as well as other vendors product.

The 2A Armament Full Mass Carrier (FMC) was designed as a high-quality, full mass bolt carrier group, with an emphasis on enhanced weight distribution. By relocating the bulk of carrier mass to the tail, the FMC keeps the firearm in a more balanced state. Weight that would normally be over the magazine well is now over the pistol grip on an AR-15 rifle when at rest. The distribution of weight is further utilized during the firing cycle as the FMC reciprocates along the plane located within the pocket of the shooters shoulder and primary support hand, instead of out in front between the magazine well, and primary support hand. The FMC can give the shooter an extremely reliable full mass bolt carrier group, with a weight distribution advantage over standard carriers on the market.
NOTE: Does not support the use of forward assist. Not compatible with full auto systems
