LMT Defense MRP-L QUAD Railed Upper 5.56x45mm/.300 AAC Blackout/6.8 SPC no BCG&CH, Black

The LMT Defense MRP-L QUAD 13.25" stripped upper receiver is the rifle-length evolution of the iconic monolithic rail platform, precision-forged from a single piece of high-strength aerospace-grade aluminum to create an integrated receiver and handguard that eliminates flex and ensures exceptional rigidity for long-range accuracy. This quad rail configuration delivers full 1913 Picatinny rails at the 3, 6, and 9 o'clock positions, offering abundant mounting space for traditional accessories like bipods, lights, foregrips, lasers, and vertical grips, paired with a continuous top Picatinny rail for unrestricted optics placement. Featuring five built-in QD sling swivel attachment points for enhanced carry versatility, it supports quick barrel changes via LMT's proprietary dual locking bolts (accessible with a standard T-30 Torx bit) and provides a true free-float barrel setup that maintains zero under heavy use or environmental extremes.Designed specifically for barrels from 14.5" up to 20" (optimized for rifle-length gas systems), this stripped upper excels in calibers such as 5.56x45 NATO and .300 Blackout, making it perfect for building precision SPRs, designated marksman rifles, duty rifles, or long-range configurations where maximum rail real estate and structural integrity are essential. The classic quad rail design harkens back to battle-proven legacy systems while leveraging LMT's monolithic innovation to reduce weight compared to add-on rail setups, improve heat dissipation during extended shooting, and deliver unmatched durability trusted by military and law enforcement professionals worldwide.Ideal for shooters who prefer the timeless functionality of Picatinny rails for heavy accessory loads or compatibility with legacy gear, the MRP-L QUAD 13.25 stands as a robust, no-compromise option in the MRP lineup for rifle-length performance and modularity.Upgrade your AR-15 platform today with the LMT Defense MRP-L QUAD 13.25" stripped upper receiver-available now at ARMSAGORA's retailers for superior craftsmanship and fast shipping.
