Jp Enterprise
A JP Enterprises tuned and polished buffer spring for AR-15 is a precision-ground operating spring engineered to smooth out the bolt carrier's travel in your rifle's buffer tube. If you're running an AR-15 with either a fixed A1/A2 stock or a collapsible M4-type carbine tube, JP's centerless-ground and polished construction delivers noticeably quieter, more consistent cycling than a standard mil-spec spring. The improved impulse feel translates to faster sight recovery during rapid fire and more reliable feeding across a wider range of loads and conditions.
The outer diameter is ground and polished to exacting tolerances, which eliminates the binding and chatter that comes with looser tolerances in run-of-the-mill buffer springs. That refinement matters most when you're pushing your rifle hard at the range or in the field—smoother operation means less wear on components, better predictability shot to shot, and the kind of reliability you actually notice when it counts. JP engineered this spring to pair with their other tuning upgrades, but it works as a standalone upgrade in any standard AR-15 platform.
Choose the rifle-length version if you're running a fixed stock with an A1/A2 buffer tube; go carbine-length for collapsible M4-pattern stocks. Either way, you're getting the same precision manufacturing that JP Enterprises applies to their complete bolt carrier groups and matched receiver sets.
