Lantac is pleased to announce the release of its range of 6MM ARC chambered rifles and dedicated E-BCG®

For the past 2 years Lantac has been working closely with Hornady Manufacturing, undertaking testing and development of products that utilise the new 6MM ARC ammunition in a variety of bullet weights. Lantac was one of the first companies to become involved with this new caliber as part of a funded military research project and has conducted extensive evaluation and development work in that time.

Lantac’s new LA-SF15 6ARC 18’’ Rifle+1 gas system (pictured) delivers 2629 FPS at muzzle with 2457FPS at 100M (109.36 Yards) and 1408 FPS at 800M (874.89 Yards). Energy is 1657 Ft-lb (2246 Joules) at 100M (109.36 Yards) and 475 Ft-lb (644 Joules) at 800M (874.89 Yards) approx.

Lantac has also developed a more compact 14.5’’ Intermediate gassed system that delivers 2483 FPS at muzzle with 2315 FPS at 100M (109.36 Yards) and 1302 FPS at 800M (874.89 Yards). Energy is 1285 Ft-lb (1742 Joules) at 100M (109.36 Yards) and 407 Ft-lb (551 Joules) at 800M (874.89 Yards) approx.

Lantac Velocity-Testing

The velocity of multiple barrel lengths was tested to create a clear picture of 6ARC’s capabilities.

The rifle is designed to offer the softest shooting experience and features a specially designed dedicated E-BCG® bolt carrier group that works with the Rifle+1 gas system and VLTOR’s A5 Buffer to deliver extremely low recoil energy, meaning that fast, repeated hits on long range targets are much easier to achieve.

Other barrel options are available for customers not wanting to use a carbon wrapped solution.

Lantacs 6ARC E-BCG® has been specially developed to manage the gas impulse delivered from a variety of 6ARC bullet weights / powder loads that will eventually be available from Hornady (the 103Gr, 105Gr & 108Gr being the initial release), it will also function with 6.5 Grendel and is available in both Nitrided and NiB (Electroless Nickel Boron) finishes.

Lantacs E-BCG® has undergone extensive trials testing and out performs other carriers with improved gas management, reduced recoil and lug stress. A 5.56mm E-BCG® Carrier and Bolt have successfully fired over 65,000 rounds of ammunition with zero failures and the Bolt was still in complete working order after MPI and X-Ray Radiography inspection.

Lantac Gas-Testing

The E=BCG® Carrier vents gas in a completely different way to standard two and three port designs. As can be seen in these frames from hi-speed testing, both the 2 port and 3 port carriers produce a plume of potentially harmful propellant gas, by contrast the Lantac E-BCG® produces a significantly reduced plume.

Lantac Recoil-Testing

Lantac undertook extensive recoil energy testing, utilising data loggers and load cells. Many carriers were tested and compared to assist in fine tuning the 6ARC E-BCG®.

Rifles are available to order now, prices vary depending on specification, please contact Lantac USA for further information.
