Jp Enterprise
The JP Enterprises Tuned & Polished Buffer Spring for AR-10/LR-308 rifles is a precision-engineered upgrade that transforms how your large-frame AR handles recoil. Built for shooters who demand smoother cycling and faster sight recovery, this spring features centerless grinding and polishing that eliminates binding and drag in the buffer tube. The result is quieter operation, more predictable impulse, and the kind of reliability you need whether you're running a precision rifle or a duty gun.
AR-10 and LR-308 shooters often overlook the buffer spring as a tuning opportunity, but JP Enterprises designed this component to work in concert with quality bolt carrier groups. The polished outer diameter slides effortlessly through your buffer tube, reducing friction and wear while improving the feel of each shot. This matters whether you're doing load development at the bench or putting rounds downrange in the field.
JP offers two versions to match your setup: a rifle-length spring for fixed A1/A2 stock configurations, and a carbine-length spring for collapsible M4-type tubes. This gives you the flexibility to build or upgrade whatever platform you already have. If you're running a JP 308 Low Mass Bolt Carrier Group, JP Enterprises specifically recommends pairing it with this tuned spring for optimal performance.

JP Enterprises offers this spring in two lengths: rifle-length for fixed A1/A2 stock configurations, and carbine-length for collapsible M4-type buffer tubes. Measure your buffer tube or match it to your stock type to select the correct version.
Yes. JP Enterprises specifically recommends using this tuned and polished spring when running their JP 308 Low Mass Bolt Carrier Group for optimal performance and tuning.
The centerless grinding and polishing reduces friction as the spring cycles through your buffer tube, resulting in smoother operation, quieter function, improved impulse feel, and faster sight recovery. You'll also experience better overall reliability.
A tuned buffer spring won't directly improve shot placement, but it does improve the impulse and recoil characteristics of your rifle, which can lead to faster sight recovery and more consistent shooting experience—especially useful for follow-up shots and rapid fire strings.
