The price point above applies to all stainless steel barrels listed in caliber options below. Worry not, though, this rifle system will accept all MWS® barrels. LMT® patented monolithic Modular Weapon System, MWS®. The only true monolithic rail platform, milled from a single solid piece of aerospace aluminum forging. It utilizes two locking bolts accessible from the side of the receiver to lock in the barrel extension. This patented technology engages the barrel extension for a full 360 degrees around the extension and makes the barrel removable within seconds with a return to zero of the same barrel. One receiver can utilize numerous barrels of varying length, material, and caliber. The MLKMWS upper receiver has 19.25" of picatinny rail on the 12 o’clock position. The remaining 7 sides provide M-LOK compatible attachment points. MWS® barrels utilize a low profile gas block and straight gas tube. They possess proprietary coating and are cryogenically treated for long term durability. The 308MWS lower receiver features LMT® ergonomic textured grip and SOPMOD stock, ambidextrous magazine catch and safety selector. As with all LMT® lower receivers, the extension tube is coated with dry film lubricant. All MWS® lowers are outfitted with a two-stage trigger group. This weapon system comes complete with flip-up sights, tactical two point sling, 3 grip panels, Magpul 20rd polymer magazine, torque wrench, and owner’s manual.
