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

Definitely feel the difference!

Looking into this buffer spring before purchasing I heard some mix reviews. I went out shooting with the brother in law before purchasing this upgrade. I shot my rifle with the stock buffer spring then put his stealth recoil spring all it took was one shot to notice the difference. Highly recommend this upgrade customer service for this company is top notch as well! Mistakenly purchased the wrong buffer weight and they got me the right spring in a few days!

Good to go

Shipping was fast. No fitment or function issues. Quality part for a really good price.


Awesome product,great service,good price. What more could you ask for? AT3 runs a tight ship as always!

Armaspec stealth recoil spring buffer system

Can't give it 5 stars yet because I've not take my SBR to the range since installing. No problems installing; the noise from the spring scraping the extension tube is gone; slight noise from the H1 weight, but applied some silicon spray and it's quiet enough. Works best if buffer detent plug and spring are removed so that the Armaspec buffer maintains physical contact with the rear of the BCG to avoid impact when cycling. I will also be replacing the existing gas block with a Superlative Arms adj gas block before taking my short bbl build to the range. Then I'll know if the Armaspec will go up a notch in rating (Note: Once I remove the muzzle brake for a linear compensator, then I'll really be able to determine what difference it makes).

Great buffer system

The Armaspec stealth buffer is an awsome alternative to the JP silent capture buffer. Well built and well priced.
