Reduce Recoil, Wear, and Unwanted Rattling

Armaspec’s Stealth Recoil Spring™ is one of the best upgrades for your AR15’s recoil system, and you can feel and hear the difference instantly.  The two-stage SRS is silent, eliminating the annoying “twang” of the stock AR15 buffer spring when the action cycles.  It also reduces recoil with the multi-spring system, resulting in a smooth, elastic feeling rather than a mechanical recoil impulse.  It’s a true innovation, all made in the USA.


  • Eliminates buffer spring rattling in the receiver extension, resulting in a cleaner sound and a smoother action

Reduced Recoil

  • The multi-stage system makes a softer recoil impulse than a standard AR15 buffer spring


  • The SRS keeps constant tension on the rear of the bolt, eliminating the need for the buffer spring retainer in new builds

I just built my 1st AR and used the Armaspec silent buffer in it . From the first shot I was stunned at how smooth and quiet it is . I just can't understand why someone would pay twice as much for the JP unit when this is such an amazing piece.

Thanks for sharing your feedback, David. We're glad you're satisfied with your purchase. Cheers!
Worth the money

I have to two of these springs, one in my ar-10 and the other in my ar-15. Definitely worth the money. Very good recoil reduction.

Thanks for sharing your feedback, Aaron. We're glad you're satisfied with your purchase. Cheers!
Fits Great

Have not fired with it yet. But I knew I needed an H3 buffer on my pistol. It dropped in and apparently functions smoothly.

Thanks for sharing your feedback, Fred. We're glad you're satisfied with your purchase. Cheers!
Best thing since sliced bread

This recoil spring system works perfect reduces recoil and sound by eliminating spring rub I now own 3 lol

Thanks for sharing your feedback, Dustin. We're glad you're satisfied with your purchase. Cheers!

Nice product, easy install but two things you should be aware of. The old style brown color "O" rings don't last very long so you might want to buy a set of spare rings and while it is possible to change weights it's VERY difficult because they use red loctite.

Thanks for sharing your feedback, Bill. Your comments were all noted. While this is not an AT3 product, we can still tap on the manufacturer to improve their products.
