The IC-SPR Upper Receiver is manufactured using the highest quality materials and comes packed with LWRC exclusive features. The heart of the IC-SPR Upper is the short-stroke gas piston system, which builds upon the original Stoner design with a variety of improvements. One of which is the elimination of hot gasses being vented into the receiver and bolt carrier group, thus reducing the required cleaning regiment. The IC-SPR also comes standard with a nickel-boron coated bolt carrier for unmatched resistance to wear and corrosion while also providing permanent lubricity.

Electroless Nickel Teflon has continually proven to outperform traditional Anodizing and Phosphate coatings by leaps and bounds! The increased reliability, corrosion resistance and ease of maintenance make this upgrade a no-brainer.
PLEASE NOTE: These uppers are being sold at a discounted rate due to minor imperfection in the base metal. These imperfections are very common but are usually hidden when anodized. Nickel Teflon does not hide them as well. In no way shape or form will these blemishes affect functionality.
