Round wire springs have been the standard since the inception of the AR-15 and AR-10 back in the 1950's. Now we are well into the 21st century, and technology and metallurgy has given way to the Flat Wire Spring and its improved performance! Compared to the industry standard round music wire or chrome silicon springs, our Enhanced Flat Wire Springs have more load on the bolt when it is in battery or fully closed. This means that we can achieve slightly increase dwell time and slow the bolt velocity as it begins moving rearwards. When the bolt is in it's furthest rearward position or locked open, out Flat Wire Springs have the same amount of force on the bolt as traditional round wire springs. What does this all mean? It means our Enhanced Flat Wire Springs act like an extra power round wire spring while cycling as easily as a standard buffer spring! Our Enhanced Flat Wire Springs also have improved vibration harmonics, meaning that bolt bounce is almost entirely eliminated and recoil is smoothed out, even when running an empty buffer or an Ultra Lightweight buffer. That annoying spring rattle or "twang" sound is greatly reduced, and often eliminated with our springs too! Bring your AR into the 21st century with a Bexar Arms Enhanced Flat Wire Recoil Spring!

Our Enhanced Flat Wire Recoil Spring 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 over the shoulder. Simply install the spring and buffer as is, and after a few shots, the spring will seat itself on the buffer shoulder.

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

  • Enhanced AR-10 Flat Wire Buffer Spring

  • Stress Relieved 17-7 PH Stainless Steel construction

    Simply the Best Spring

    Posted by SMITH on Jun 9th 2020

    Simply, THE BEST. These springs are absolutely the best springs for AR platforms. I have one of these in each AR10 (carbine, mid, rifle) and they’ve made them run a lot smoother. Far less “twang”, and “bounce”. The customer service you get from Bexar Arms is unparalleled. A phenomenal product, excellent customer service, perfectly priced, and fast shipping. I’ll always recommend Bexar Arms! #Flatisjustice

    Gets the job done

    Posted by Sam on Jun 5th 2020

    Bought this flat spring to replace my round spring. The flat spring from bexar significantly reduces the "twang" noise from your spring. Add a little grease and your good to go. No failures whatsoever

    Fixed my AR-10

    Posted by Hunter on Jun 2nd 2020

    After struggling with (what I thought were) light primer strikes on my AR-10, I saw this as a nice upgrade, not even expecting it to turn my reliability from 1 FTF every ~3 rounds into flawless shooting, but that’s exactly what it did. Turns out my problem was the old spring lacked the power to close the bolt consistently, and this fixed it. Plus the (very loud) spring noise is gone - when pushing hot 308 loadings, the old spring could be quite obnoxious. 100% would recommend
