JP .223 Enhanced Gas Rings - As a replacement for traditional three-piece gas rings the JPEGR-223 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 small-frame 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.

Accessory Tactical Rail: 2 (w/o Backer Plate) - 2 tactical rail segment without backer plate for accessory mounting on JP Hand Guards - Usage/Compatibility: 3:00 9:00 and 45° positions on RC hand guards 6:00 position on all JP hand guards

JP Enhanced 9mm AR Bolt - Machined to the same exacting tolerances as our bolt carriers this second generation 9mm bolt assembly is an entirely new design that eliminates the need for a central mass (slug) to readily function with our 9mm JP Silent Captured Spring without compromising bolt weight and reliability. In fact when combined with our JPSCS-9MM you have the heaviest most reliable 9mm operating system that dramatically reduces bolt bounce while improving accuracy. - This bolt assembly is .9 oz. heavier than the Rock River Arms 9mm bolt with its central mass removed. When used in conjunction with the Silent Captured Spring the complete JP 9mm operating system is slightly heavier than the complete RRA bolt and buffer some of the bolt mass having been transferred to the SCS in our system. - Features: - Reduced stroke length for faster firing impulse when used with JPSCS2-9MM - Corrosion-resistant 416SS construction - Designed for optimal function with JPSCS2-9MM for a heavier operating system that reduces bolt bounce while improving reliability and accuracy - Tighter firing pin channel to reduce pin wear - Rock-hard nitride finish provides remarkable natural lubricity and a fine cosmetic finish - Includes firing pin and retainer pin

JP LMOS™ Bolt Carrier - Small-Frame (.223) - Stainless Steel - Polished Finish - Includes JP Enhanced Gas Ring - Not for use in .308 AR-type rifles. - Weight: 6.75 oz. with key installed.

JP Low Mass Operating System Bolt Carrier - Large-Frame (.308) - Stainless Steel - Polished Finish - Requires DPMS-pattern bolt firing pin and cam pin. - Includes JP Enhanced Gas Ring - Weight: 10.82 oz. with key installed.

Custom Centerless Ground and Polished Operating Spring - Small-Frame Carbine Length - Precision centerless ground and polished operating springs offer a smoother and quieter operation in AR buffer tubes. Improved impulse feel results in faster sight recovery and improved reliability.

This spring kit will yield a 3.5-4.0 lb. trigger pull with JP Fire Control parts. This kit is intended for use with JP trigger parts and will not necessarily yield substantial change on standard AR-15 trigger components.
