JP Enterprises Enhanced Gas Ring .308 Caliber

Enhanced Gas Ring Features As a replacement for traditional three-piece gas rings the JPEGR-308 utilizes a one-piece design similar to the Mcfarland rings. Unlike the Mcfarland rings though our precision-ground gas rings are engineered to precisely suit DPMS-patterned carrier group components such as our own JP EnhancedBolt. After testing numerous minute grind callouts the final JP Enhanced Gas Rings spec is the perfect balance of a solid gas seal with a very low-friction relationship between rings and bolt carrier. Reducing the resistance between these components directly results in an overall increase in the rifle s operational window while the edge of the rings utilizes the cycling action itself to scrape the walls of the carrier helping shed fouling with every shot. The JPEGR-308 is not compatible with large-frame Armalite bolt assemblies.
