M16 Full Auto Style for increased mass and lock time.

This BCG works in ANY standard AR15 receiver.

See full specs here

Lantac's 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 coefficent 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.

Run with Confidence!

I ordered one of these when I first heard about them because I needed one for a new build. Paying was easy and shipping very fast. So I figured I may as well get a top of the line BCG since it does most of the work for moving parts. Boy am I happy with it, runs cleaner than my others. This also give me confidence knowing it has the capability to run full auto even though I don't see ever doing that. I figure if it can run wide open then it is a breeze running with my one shot one hit mentality. Firearms 4 less is easy to deal with. Thanks


Runs clean!

Purchased one of these and was skeptical of the "runs cleaner" claim but it's real! I think the forward facing gas ports must help with that as it seems to be cleaner than my other NIB BCGs after the same amount of shooting. The domed cam pin makes sense too, though I cannot prove it since I'd already used my upper receiver extensively. Great product and delivery was fast. Thanks Firearms 4 Less!
