JP Enterprises Enhanced Gas Ring .308 Cal

JP .308 Enhanced Gas Rings - One-Piece Design for DPMS-Pattern BCGsDesigned to replace traditional three-piece gas rings, the JP .308 Enhanced Gas Ring features a precision-ground, one-piece construction engineered specifically for DPMS-pattern bolt carrier groups like the JP EnhancedBolt. Unlike McFarland-style rings, these are optimized to deliver a precise gas seal while maintaining minimal friction between the bolt and carrier.The low-resistance design expands the rifle's operational window and improves reliability. As the ring cycles, its edge scrapes fouling from the carrier walls, promoting cleaner operation with each shot.Not compatible with large-frame Armalite bolt assemblies.
