Description

The LMT Defense 16" Stainless Steel 350 Legend MRP-L Barrel Assembly (L7KA1S) brings LMT's renowned Monolithic Rail Platform modularity to the .350 Legend cartridge — America's most popular straight-wall hunting cartridge. LMT designed this barrel specifically for hunters and sportsmen who want to utilize the MRP's quick-change barrel capability to transform their LMT AR-15/MRP into a capable medium-to-large game hunting platform. The barrel ships with a 10-round .350 Legend Duramag and does not require a new bolt carrier group — it installs directly into any LMT MRP-L upper using your existing 5.56 BCG. The stainless steel construction with 1:16" twist rate is optimized for the wide range of .350 Legend hunting projectiles, while the carbine-length gas system uses a standard straight gas tube and pinned gas block for reliability.
