JP Enterprises 9mm Bolt Carrier Group - JPBC-9SL Review

About JP Enterprises 9mm Bolt Carrier Group - JPBC-9SL

JP 9mm AR EnhancedBolt™ Assembly Short-Stroke Version Machined to the same exacting tolerances as our bolt carriers, this third generation 9mm bolt assembly 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 Silent Captured Spring, you have the most reliable 9mm operating system that dramatically reduces bolt bounce while improving accuracy. New to this revision is compatibility with our line of short-stroke Silent Captured Springs. This bolt assembly will provide reliable last-round lockback with any compatible receiver such as our GMR-15™. Features: Last-round lockback compatibility with both standard and short-stroke SCS Corrosion-resistant 416SS construction Designed for optimal function with our Silent Captured Spring 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 Compatibility Use of this bolt requires a 9mm Silent Captured Spring or 9mm buffer and spring. It will not function with standard AR-15 buffer components. This bolt assembly is compatible with Glock pistol magazines. This bolt assembly is not compatible with Colt SMG-style lowers and magazines. This bolt assembly is also compatible with our JP side-charging uppers.
