There are a lot of ways to improve the performance of your AR system. Muzzle devices, reduced mass bolt carrier groups, and gas tuning all contribute to an improved operating experience. For those of you who are looking for just a little more, JP Enterprises offers the JP Enterprises Polished AR-15 Buffer Spring. This quality buffer spring will make the operation of your AR system smoother and more reliable than any OEM buffer tube spring can.

All AR-15 Buffer Springs Aren’t Created Equally

The JP Enterprises Polished AR-15 Buffer Spring is a high quality, centerless ground buffer tube spring for the AR-15. It is available in either carbine length or rifle length, perfect for your small-framed rifle build. These springs are precision ground and polished to provide a much smoother cycle than your original equipment AR spring. The superior quality of JP’s buffer spring allows it to work smoothly within the receiver extension without dragging or “twang.”

What Difference Can a Spring Make?

The buffer system of the AR-15 has an important job, it dissipates a lot of the recoil force of the weapon, allowing for a less violent kick and cycling of the AR system. If a spring is rough and catches inside the receiver extension, the buffer system does its job with less efficiency. Likewise, a soft or worn spring won’t do its job as well, and the system will react more violently than it would with a properly functioning spring. Even systems with “good” springs can benefit from an upgrade in springs. The superior polish and strength of the JP Enterprises Polished AR Buffer Spring will reduce the felt impulse of your rifle on firing, allowing you to remain on target for excellent follow-up speed and greater accuracy, shot after shot.

    Though aesthetically pleasing that is hardly why one purchases a buffer spring. I chose this one because of JP Enterprises is known for quality parts, I was not disappointed with this, this is the quietest spring I have ever ran. Great product!

    I have a overgassed 10.5” ar build. After reading about the slightly stronger spring rate of this product I decided to give it a try. Took away 75% of the overgassing problem. Will be installing a 4 oz buffer next (one step up from the standard 3 oz). Well made spring
