The LMT L7Y1A MRP 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 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, and MWS. CQB receivers have a short handguard that fits barrels between 10.5” and 18”. The full-size MRP 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 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.
