The LMT L7RA1A full-size Receiver is a bare monolithic quad-rail upper receiver that fits intermediate-caliber cartridges with barrels between 14.5” and 18”. 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.
The CQB 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 CQB receiver is a fantastic place to start an AR build, especially when you want that barrel changing ability.
