LANTAC .308/7.62X51MM Enhanced Full Auto Style Bolt Carrier Group NiB Coated

The following is a Press Release from LanTac-USA:

LANTAC E-BCG™, Enhanced Bolt Carrier Group.

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.

LanTac 308 EBCG 001

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.

LanTac 308 EBCG 002

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.

LanTac 308 EBCG 003

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.

LanTac 308 EBCG 004

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.

LanTac 308 EBCG 005

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.

SHOT Show 2015 – VooDoo Innovations

SHOT Show 2015 Voodo Innovaions Barrels-1000

VooDoo Innovations was featured this year in the Adams Arms booth at SHOT Show.

They were featuring a long line of varying profile and length AR barrels as well as an one piece Direct Impingement Bolt Carrier.  There will be no concerns of the gas key coming loose or a poor staking job with this one.  VooDoo Innovations is also offering a low-mass BCG, which unfortunately was not available for viewing while I was at the booth.

SHOT Show 2015 – LanTac USA

LanTac USA, who has been mostly known for their Dragon Muzzle Brakes, had a booth full of new awesomeness available for all to see….and for one sticky fingered thief, a BCG to take home.

SHOT Show 2015 LanTac USA Blast Mitigation Device (BMD)-1000
LanTac USA Blast Mitigation Device (BMD)

LanTac USA’s Blast Mitigation Device, or BMD, is a removable shroud of sorts that can be placed over the Dragon Muzzle Brake to control the side blast from the Dragon and away from the shooter.  The BMD is quickly removed from the Dragon by pressing two release buttons on either side of the device.

This Enhanced BCG is the brother of the Ti Enhanced BCG that was stolen from the LanTac booth at SHOT.  The stolen version was a one-off version without Forward Assist serrations and was made of Titanium.  Click HERE for more info from LanTac regarding a description of the stolen BCG.  They are offering a reward.

The Enhanced BCG is M16 Full Auto style, machined from 8620 steel with a Shot Peened (SP) bolt and is Magnetically Particle Inspected (MPI).  The entire carrier assembly is NiB, electroless NiB coated with the patented advanced UTC EXO process.  The carrier features forward gas porting with enlarged gas vents to run cooler and cleaner and reduces the pressurization of the receiver.
