There are a lot of parts that can be upgraded to improve performance or that might need replacing after you’ve used a rifle for a while. You might tinker with triggers and swap out safety selectors on a fairly regular basis, but how often does your buffer spring really cross your mind? It’s time it did. Strike Industries AR-15 flat wire buffer spring is the drop-in improvement you’ve overlooked for too long. 

AR-15 buffer springs tend to be something of a weak link in the weapon system. Over time the OEM springs weaken, and can fail, bringing the service life of your rifle to an abrupt end. Strike Industries’ AR-15 flat wire buffer spring is made from 17-7 steel that has been cryo-treated to last longer and perform more reliably than its predecessors. 

The space between spring arcs is larger, and will not compress with use. You’ll enjoy more consistent performance, increased bolt load and much smoother cycle than with OEM springs. The flat wire buffer spring controls harmonics and vibration allowing the shooter to get follow-up shots off more quickly. Not only is AR “bounce” virtually eliminated, but the irritating “twang” so many shooters complain of is a thing of the past when you use this AR-15 buffer spring. 

Whether you’re building a new system or just looking to replace a worn AR-15 buffer spring, the Strike Industries Flat Wire AR Carbine Buffer Spring is the only buffer spring you need to consider for your standard length AR build. Not only does it outperform OEM springs, but it does it without breaking the bank.

  1. Another SI winner 5 Star Review

    Posted by on 12th Dec 2017

    These springs are in all three of my AR platforms (16" 556, 12.5" 556, and a 9" 300 blk) and The improved bolt load alone is worth it. It is subtle but you will feel the action smooth out both charging manually and during firing cycle. The benefit of the twang dampening is icing on the cake. $17 at + WT fast reliable shipping and no regrets.

  2. Great Upgrade 5 Star Review

    Posted by on 28th Aug 2017

    This spring has a much more linear feel to it when you cycle the charging handle - not as "bunchy" feeling as a regular spring. It fixed the short-stroking issue I was experiencing on my .223 Wylde-chambered AR when firing some of the weaker .223 ammo. It also has noticeably less "sproing" sound than a standard spring. I think I will eventually upgrade all of my AR's to a Strike Industries flat spring.

    FWIW I've also bought one of the Tubbs flat springs and have to say that I like the Strike Industries spring better. The Tubbs seems stiffer - so that may or may not be what you're looking for.

  3. Spring 1 Star Review

    Posted by on 26th Jun 2017

    All I can say is the A. R. Functioned No different than. A DPMS spring.
    I was trying to tune the rifle with springs and buffers for accuracy and function Groups opened up to inch and a half with this spring so put back the old spring now groups three quarters of a minute
    This is a match rifle
    It did help with the noise during function cycle but that is all the good I can say about it

  4. Quiet 5 Star Review

    Posted by on 15th Jun 2017

    This spring stops your AR-15 from sounding like a "pogo stick" It is also a bit longer and provides a bit more force closing the bcg. I will assume like flat magazine springs it will last longer due to it not retaining a "memory" from constant compression as round springs are said to do. I will also mention I got this at a great price as compared to other competitors.

  5. Great spring, Great deal 5 Star Review

    Posted by on 22nd Apr 2017

    Great price, fast shipping. Awesome spring. Install was a breeze, slid right in. Immediately could feel the difference from a stock spring and it was even better after I shot it. Cycles smoother than ever. Could not be happier with the spring and WingTactical.

  6. Don't know what your missing! 5 Star Review

    Posted by on 17th Feb 2017

    If you don't have one of these springs in your AR, your missing out on about 15% of your performance & pleasure!
    These springs get rid of the "twang" so you can enjoy the bang!

    Posted by on 2nd Jan 2017

    Installed it on my rifle fired some round worked great. I could definitely tell there was less spring twine. Worth the money.

  8. Very Nice 5 Star Review

    Posted by on 30th Dec 2016

    Easy to install, and shouldn't have to worry about changing it out for a very long time. I haven't fired any rounds since I installed it(Install was beyond easy) but look forward to doing so this weekend. From what I've read, great way to upgrade your rifle's performance on the cheap!
