The LMT L7Y1A MRP-L Receiver is a bare monolithic MLOK upper receiver that fits intermediate-caliber cartridges with barrels larger than 14.5”. By adding your own LMT barrels, you can transform this receiver from a combat carbine to a full length SPR in under a minute. You can also transition to .300blk or .224 Valkyrie just as easily. With the LMT MRP-L receiver, you have the power to configure your rifle exactly how you need it without buying multiple guns.

This full-size MRP receiver is one of three available sizes: MRP CQB, full-size MRP-L, and MWS. CQB receivers have a short handguard that fits barrels between 10.5” and 18”. The full-size MRP-L receiver uses the same cartridges as the CQB receiver but has a larger handguard for rifle-length gas systems and 14.5” or longer barrels. Finally, the MWS is the .308 full-power equivalent. With a wide range of available calibers, the MWS makes a great hunting rifle, battle rifle, or DMR—and transition between them with simple barrel changes.

This receiver also has a monolithic top rail for fully variable optics mounting, 5 available QD points, a forward assist, and incredible precision machining. Overall, the LMT MRP-L receiver is a fantastic place to start an AR build, especially when you want that barrel changing ability and smooth-shooting rifle-length gas system. This version uses an MLOK handguard for accessory attachment, but Quad-Rail and Slick receivers are also available.
