One receiver can utilize numerous barrels of varying length, material, and caliber. The upper receiver has 19.25″ of picatinny rail on the 12 o’clock position. The remaining 7 sides provide M-LOK compatible attachment points. MARS-H barrels utilize a low profile gas block and straight gas tube. They possess proprietary coating and are cryogenically treated for long term durability. The MARS-H ambidextrous lower receiver features our EDM machined two-stage trigger, winter trigger guard, endplate with QD swivel point, LMT® ergonomic textured grip, and SOPMOD stock. The ambidextrous features include bolt catch and release, magazine catch, and safety selector. As with all LMT® lower receivers, the extension tube is coated with dry film lubricant.
