ICU5B14PSPR
The LWRC IC-SPR 5.56mm NATO 14.7" Complete Upper Receiver features a 14.7-inch barrel with a 1:7 twist rate, optimized for 5.56mm NATO ammunition. It has a P&W (Pinned & Welded) barrel, making it compliant with legal length requirements. This LWRC ICU5B14PSPR upper receiver is designed for high-performance, precision shooting, and includes LWRC's reliable short-stroke piston system, which reduces maintenance and enhances reliability. Finished in black, it is ideal for those looking to upgrade or build a tactical rifle with excellent accuracy and durability.
The LWRC IC-SPR Upper Receiver is engineered with top-tier materials and boasts exclusive features. At its core lies the short-stroke gas piston system, an advancement of the original Stoner design. Notably, it minimizes the venting of hot gases into the receiver and bolt carrier group, reducing the need for frequent cleaning. Moreover, it comes equipped with a nickel-boron coated bolt carrier, ensuring exceptional resistance to wear and corrosion while providing enduring lubrication.
Featuring a heavy-profile, cold-hammer forged barrel treated with black Nitride, the LWRC IC-SPR Upper Receiver is available in 14.7" and 16.1" lengths, each adorned with distinctive spiral fluting. Beyond aesthetics, the spiral fluting reduces weight by up to 20% and enhances cooling by increasing surface area. Additionally, it boasts a 12" user-configurable rail system, enabling customizable placement of accessory rails while maintaining a low-profile, ergonomic design. Accessing the gas-piston system is swift, requiring the loosening of two thumb screws and removal of the top rail section.
