The LMT Defense L129A1 is designed for superior accuracy and modularity, featuring LMT’s patented monolithic MWS® upper receiver, milled from a single aerospace aluminum forging. This system uses two side-accessible locking bolts to secure the barrel extension, providing 360-degree engagement and allowing for quick barrel changes while maintaining consistent return-to-zero performance.
The CQBMWS upper receiver offers extensive mounting capability, with 19.25 inches of uninterrupted Picatinny rail at the 12 o’clock position, 9-inch side rails at 3 and 9 o’clock, and a 7-inch rail at 6 o’clock for full accessory integration. The MWS® barrels feature a low-profile gas block and straight gas tube, enhanced with a proprietary coating and cryogenic treatment for long-term durability and heat resistance.
The LM308MWS lower receiver is equipped with a precision EDM-machined two-stage trigger, ambidextrous magazine release and safety selector, and an LMT SOPMOD stock for enhanced ergonomics and control. The QD swivel endplate and textured LMT ergonomic grip ensure a secure, adaptable handling experience.
