Lantac LA-SF15TM 6MM ARC Chambered Rifle & Dedicated E-BCG

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.

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.

Lantac’s 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.

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 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.

    Developing and pushing a new boutique round for the AR platform is foolish right now with the ngsw 6.8 caliber in the pipeline.

    Not to mention existing 6.5 rounds fills 90% of this performance space with far less cost and greater parts and ammo availability.

    • Vin says:

      Disagree

    • Gear Guy says:

      Are you a combat developer Joe? If not, then why would it matter whether or not a new round is introduced, especially since it performs much like the 6.5CM, but in an AR15 platform, not the AR10/SR25 platform?

    • PNWTO says:

      It would seek that a multi-year T&E conducted by DoD users and the subsequent large-ish acquisition program for this cartridge would disagree with you.

    • Gear Guy says:

      Are you a combat developer Joe? If not, why does it matter if a new round is introduced? Especially since it performs much like the 6.5CM, but utilizes the AR15 platform, not the AR10/SR25.

      • Joe says:

        It’s 6.8 SPC v2.0

        Someone in socom said “wouldn’t it be cool if…” And then marketing runs with it and says the combat ninjas are using it with no backup.

        If you want something long range just go with a 6.5 creedmoor that all the cool guys are confirmed going with.

        All these newer specialty rounds will be dropped like Tammy the stripper’s promises to wait once NGSW is a go and everyone gets on the bandwagon.

    • SSD says:

      What makes this interesting, along with 264 USA is that these intermediate cartridges can be used in the AR15 platform.

    Thanks for the science, Boys.

  3. Mick says:

    So I thought that was the point of 6.5mm Grendel…
    Is this just another attempt to “do it better” or is there something else special about this?

  4. Nic says:

    I think the new 6mm ARC is the best overall cartridge design for the AR-15 platform to date. The 5.56 is anemic and the 6.5, 6.8 offerings feel slow and clunky. This is what the 6.5 Grendel should have been to begin with. If I were going to war with a M4, the new 6mm ARC would certainly be confidence inspiring with the ballistics it provides and the energy it carries. It definitely puts the 5.56 to shame. I don’t see it as ‘Just another new Cartridge’. I see this as what people have been trying to do for the AR-15 for years and just never got right until now. I’m stoked!
