Enhanced AR 15 Buffer Spring

The Enhanced AR 15 Buffer Spring is an upgraded recoil spring that replaces the factory action spring in your buffer tube. A stronger ar 15 buffer spring smooths the bolt carrier’s travel, supports more consistent cycling, and holds up better to wear than a standard spring, especially in high-round-count or forced-reset-trigger setups. It is a low-cost staple in our AR-15 buffers and trigger parts.

A buffer spring is an ordinary rifle part. Always follow your state and local laws, and you must be of legal age and eligible to purchase.

Specifications and fitment

More reliable cycling and longer service life

An enhanced action spring is built to resist the fatigue and binding that can develop in a worn factory spring. It helps reduce felt recoil and keeps the bolt carrier cycling smoothly, which matters most when the rifle is running hard. Paired with a heavier buffer such as the H3 carbine buffer, it gives you a tuning point for dialing in suppressed or unsuppressed performance, the kind of build-tuning depth you will find across the whole FRT triggers range.

Frequently asked questions

Will it work with a forced reset trigger? Yes. The enhanced spring is a good match for forced reset trigger builds such as the FRT-15, where consistent reset and cycling are important.

Can I run it with a heavy buffer? Yes. It works well alongside heavier buffers like the H3, letting you fine-tune the action for your barrel length and gas system.
