LMT Defense MRP-L Quad 9.25″ Upper Receiver Features
This monolithic upper receiver is constructed from a single piece of forged aerospace aluminum, providing enhanced strength, improved rigidity, and increased accuracy over traditional two-piece designs. The proprietary barrel locking system, secured by two side-accessible locking bolts, ensures rapid and repeatable barrel changes with a simple T-30 Torx bit.
The quad-rail design at the 3, 6, and 9 o’clock positions offers ample space for mounting accessories, while five QD sling swivel attachment points provide versatile sling options. This receiver is compatible with LMT’s monolithic barrel assemblies, utilizing a low-profile gas block with a straight gas tube.
