Round wire springs has been the standard since the inception of the AR-15 in the 1950's. Compared to round wire springs made of music wire, stainless steel, or even chrome silicon, our Enhanced Flat Wire Spring places more load on the bolt when it is in battery. This equals slightly increased dwell time and lower bolt velocity. When the bolt is locked open, our Enhanced Flat Wire Spring places the same amount of force on the bolt as traditional round wire springs.

Why does this matter you may ask? Our Enhanced Flat Wire Spring acts like an extra-power round wire spring, yet cycles as easily as a standard buffer spring! The higher preload and lower compressed load also means recoil is smoothed out and bolt bounce is typically eliminated, even when running ultra-lightweight buffers. That annoying spring rattle or "twang" sound is greatly reduced or eliminated, too!

Bring your AR into the 21st century with a Bexar Arms Enhanced Flat Wire Recoil Spring!

Our Flat Wire Recoil Springs may be a tight fit over the shoulder of your buffer. This is completely normal, and it is not necessary for your to force the spring onto the shoulder. Simply install the spring and buffer as is, and after a few shots, the spring will seat itself on the buffer shoulder. Our Flat Wire Recoil Springs are only compatible with Mil-Spec style buffers with slim shanks and pronounced shoulders. Buffers with straight shanks and no shoulder, or a minimal amount of shoulder do not have enough clearance to function correctly with our Flat Wire Recoil Springs.

100% Made in the USA!

A note from Phillip: If your spring still has some rattle or twang once installed, try using some of your favorite automotive grease on the buffer and spring. I personally prefer the full synthetic Lucas X-TRA Heavy Duty "green" type of grease. Your spring should now be completely twang free!
