JP Rifles 9mm BCG/Silent Captured Spring Combo

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 JPSCS2-9MM, you have the heaviest, most reliable 9mm operating system that dramatically reduces bolt bounce while improving accuracy.

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
◾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
◾High-energy tumble process offers a finer cosmetic finish

Compatibility

The JP 9mm bolt assembly is compatible with both Colt SMG-style magazines and Glock pistol magazines.

The bolt assembly is also compatible with our JP side-charging uppers.

The Gen 2 9mm SCS requires an open channel in your 9mm bolt assembly for the guide rod to pass during fire. For most bolts, this will require you to remove the pinned-in central mass. To function with the SCS, this central mass must be removable, and the bolt must still be at its full length without it. Refer to the instructions link below for more.
