By now most people are familiar with the LANTAC E-BCG. I personally use it in my suppressed SBR and it is simply an amazing BCG. They’ve been leaking pics of the .308/7.62×51 version for a while now and all of a sudden…the big boys are finally available. Make no mistake, this is not your average BCG and is priced accordingly. If you’re looking for simply the best .308 BCG, this is it. Pics and details are below.
AR10 Full Auto Style for increased mass and lock time.
Our new BCG is precision machined from 8620 Steel with a 9310 Precision Hard Ground, Magnetically Particle Inspected Bolt.
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 position within the buffer tube at the time of cycling and allows for a flatter more controlled reciprocation of the assembly.
All critical dimensions are hard turned / ground after heat treat.
All E-BCG’s feature the LANTAC CP-R360-H™ 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 weight helps to increase lock time with 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.
