Lantac Full Mass Full Auto Enhanced Bolt Carrier Group For AR15 Style 5.56 / .223 Rifles - Nickel Boron

The Lantac Enhanced Bolt Carrier Group is a M16 full mass (11.7 oz) full auto bolt for increased mass, increased lock time and smoother operation. It 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 UTC EXO process, unlike standard NiB coatings. This offers extreme lubricity with a friction coefficent of .04 and surface hardness of 68-72 Rockwell C.

The carrier's patent pending design features unique shrouded and forward facing gas ports that have also been re-sized so that gas is vented differently than 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. Gas keys are properly staked at four points and only grade 8 fasteners are used in assembly.

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 and rounded head reduces wear within the upper receiver.

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.

Awesome

When I decided to take my IWI z15 rifle up a notch, I stumbled across this BCG and had to have it. I have no regrets. The fit and finish are perfect. The machine work is top notch and clean with all sharp edges beveled nicely and the Nickel Boron finish is beautiful. Definitely adds a lot of that "pride of ownership" knowing I have one of the best BCGs on the market among other things. Very Happy. Definitely don't hesitate to try one. Even if it doesn't fit your budget they have upgraded Mil-Spec Bolts too that are less expensive and probably just as good. Just do it!

Awesome

I built my first ar and wanted to spare no expense, read the reviews and decided this was the way to go, and it's no joke slippery out of the box! So I put my gun together go to cycle and the bcg gets stuck and mind you I have the Lantac upper as well. So I immediately email Lantac directly, on a Sunday. The very next morning I get an email from a Lantac engineer requesting a number to reach me, didn't want to play the email game. The gentleman walked through everything with me to fix the issue turns out the mil-spec buffer I ordered wasn't mil-spec and it fixed the issue. Now within the conversation the gentleman was calm collected and said no matter what we'll get it fixed or do right by you, he gave me his personal cell to call if I have any further issues. So overall the product is superb and the company is even better!

This BCG is as slick as .... Well made and smooth as glass. Running in a Lantac upper but it can be run in a normal upper as well. Using the enclosed frog lube and just wiped clean. No scrubbing needed.
