JP Enterprises Short Lock 9mm Bolt Assembly - Black QPQ

Machined to the same exacting tolerances as their bolt carriers, this third generation 9mm bolt assembly eliminates the need for a central mass (slug) to readily function with their 9mm JP Silent Captured Spring without compromising bolt weight and reliability. In fact, when combined with their 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 their line of short-stroke Silent Captured Springs. This bolt assembly will provide reliable last-round lockback with any compatible receiver such as their GMR-15™.

Features:

• Reduced stroke length for faster firing impulse when used with JPSCS2-9MM
• Last-round lockback compatibility
• Designed for optimal function with JPSCS2-9MM for a heavier operating system that reduces bolt bounce while improving reliability and accuracy
• Rock-hard nitride finish provides remarkable natural lubricity and a fine cosmetic finish
• Includes firing pin and retainer pin
