This receiver is the starting point for your LMT MRP-L Carbine build. Think of it as a blank canvas—or a swiss army knife.

  • CQB Receiver with 12.5”-18” Intermediate Barrel Compatibility
  • Larger internal ID for use with shorter barrels and smaller suppressors
  • 5 QD Sling attachment Points
  • Precision Machined Receiver with MLOK handguard
  • True Monolithic Top Rail
  • Forward Assist
  • Black Finish

The LMT L7SX1A Carbine Receiver is a bare monolithic M-LOK upper receiver that fits intermediate-caliber cartridges with barrels between 12.5” and 18”. Additionally, this new model features a larger internal diameter making it a great option for shorter barrels with suppressors attached. By adding your own LMT barrels, you can transform this receiver from a door-kicking short barrel 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 CQB receiver, you have the power to configure your rifle exactly how you need it without buying multiple guns.

This Carbine receiver is designed to fit barrels 12.5” and greater. 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 Carbine receiver is a fantastic place to start an AR build, especially when you want that barrel changing ability. This version uses an M-LOK handguard for accessory attachment, but Quad-Rail and Slick receivers are also available.
