Description

The LMT Defense MRP-L Quad Rail (Picatinny) 13.25" AR15 Upper Receiver (L7RA1A) features the patented LMT Monolithic Rail Platform (MRP™) — the upper receiver and handguard are machined from a single piece of forged aerospace-grade aluminum, eliminating flex and providing an unrivaled platform for accessories and optics. The MRP-L Quad Rail 13.25" provides an extended full Picatinny rail configuration on all four sides, maximizing accessory real estate for 16" and longer barrel builds. Perfect for patrol rifles, DMR configurations, and any shooter requiring extensive Picatinny mounting space for lights, lasers, vertical grips, and bipods.

The LMT MRP barrel swap system uses a proprietary two-bolt locking mechanism accessible from the right side of the receiver. A standard T-30 Torx bit is the only tool required — enabling fast, no-armorer barrel changes in the field. This receiver requires LMT monolithic barrel assemblies with low-profile gas blocks and straight gas tubes. Barrel not included.
