MARS-LS PDW grade lower
Reviewed on April 23, 2026Verified with Build

LMT MARS-LS PDW lower mates to a Colt or BCM upper with zero gap, you can pivot the takedown pin with no rattle. The ambi controls feel identical on both sides which is what you want. LMT trigger that comes with it is crisp. Premium lower price but warranted.

LMT MARS-LS is the standard
Reviewed on March 18, 2026Verified with Build

LMT MARS lower is the benchmark for ambi controls. Mag release, bolt catch, safety all work on both sides without any modification. Mate to any quality upper has zero play. PDW version comes complete with the LMT trigger which breaks at 5 pounds clean.
