ICU5PBC16SPR
The LWRC IC-SPR 5.56mm NATO 16.1" 1:7" 1/2x28 Bbl Patriot Brown Complete Upper Receiver ICU5PBC16SPR features a high-quality, aerospace-grade construction with a self-regulating short-stroke gas piston system. Its NiCorr-treated, cold hammer-forged spiral fluted barrel is lighter and enhances heat dissipation. The LWRC ICU5PBC16SPR upper includes an LWRCI Bolt Carrier Group, Ambidextrous Charging Handle, H2 Buffer, Carbine Length Action Spring, and Skirmish Back Up Iron Sights, offering superior reliability and performance.
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.
