Lantac LA-SF15™ 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 and PROOF Research 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 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.
