Lewis Machine and Tool, or LMT, have made a name for themselves in the premium firearms and accessories market, and weapons like the MARS are a big part of the reason why. At its core, the MARS is basically an AR10: it’s a direct gas impingement design in .308 caliber. But, to get the bigger picture of what makes the MARS such an excellent platform, you have to look beyond the mere specifications and take a look at the excellent quality on offered by LMT.


  • .308 Caliber
  • 20” Barrel
  • 9.48 lb. Weight
  • 1:10 Twist Rifling

This is, in effect, a premium AR 10. With the solid foundation of the design, LMT takes the quality up to the next level with an extremely solid handguard that not only offers you plenty of M-lLOK space but also has a full-length 1913 rail on the top that will almost certainly retain zero. Additionally, the addition of a two-stage trigger, high quality stock, and premium pistol grip make this an excellent option for people who want a modern battle rifle. Just add an optic and this is a great option for people looking for an AR 10.
