LANTAC’s new E-BCG has a few tricks up its sleeve. Basically, they claim that it deals with gas differently than other carriers and that the benefits of how it deals with gas are two fold: decreased blow-back when using a suppressor and reduced recoil/muzzle rise.
According to LANTAC the E-BCG has “Redesigned gas ported carrier, shrouded primary port, enlarged and forward angled secondary ports.” They also state on their Facbeook Page that…
The new gas porting results is a much flatter shooting carrier, as gas is bled off differently, it also dumps more of its gas forward and out of the ejection port opening. Due to this feature suppressed short barrel rifles do not seem to suffer from as much pressurization. In testing we were able to shoot a 7.5” 556 rifle with suppressor fitted in full auto and feel no gas to the face. This was with a .0635” gas port and pistol gas and standard charging handle.
Unsuppressed and longer barrel rifles benefit from smoother, flatter operation and increased lock time.
The E-BCG also features an enlarged tail to aid “ in receiver bore alignment and aids in bolt lock up position consistency.” The carrier is constructed from 8620 steel, the MPI tested bolt is constructed from Carpenter 158, and the entire unit is Nickel Boron coated. The extractor is fitted with a spring insert along with an o-ring and the gas key is properly staked.
