Lantac BCG Overview
AR10 Full Auto Style for increased mass and lock time.
Our DPMS Style 308 BCG precision machined from 8620 Steel with a 9310 Precision Hard Ground Bolt.
The entire carrier assembly is NiB, Electroless Nickel Boron coated with the patented, also 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 re sized so that gas vented differently to a standard carrier.
Lantac E-BCG. It cycles both subs and supers flawlessly in a .300 blackout pistol. Better than any “mil-spec” BCG because of its gas porting. January 30, 2022 7:14 pm Reply Ed C. PSA made the list of best BCG but DD isn’t on the list? November 22, 2021 4:44 pm Reply T-Roy.
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 also allows for a flatter more controlled reciprocation of the assembly.
All critical dimensions hard turned / ground after heat treat.
All E-BCG’s® feature the LANTAC CP-R360-H™ patent pending domed cam pin that machined from 17-4PH Stainless Steel.
The ultra smooth head reduces wear within the upper receiver.
The BCG’s weight helps to increase lock time with smoother operation.
Gas keys properly staked at four points and only grade 8 fasteners used in assembly.
The E-BCG’s® forward porting and also 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.
