Product description
Reduce Recoil, Wear, and Unwanted Rattling
Armaspec’s Stealth Recoil Spring™ is one of the best upgrades for your AR15 or AR10 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.
These springs are the new Gen 4 SRS for 2023. There may be small changes to the product’s overall appearance.
Features:
- Silent: 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
- Self-Contained: The SRS keeps constant tension on the rear of the bolt, eliminating the need for the buffer spring retainer in new builds
Which Stealth Recoil Spring do I need?
Generally, most users can follow these guidelines when replacing their recoil system – but each firearm is different, especially when looking at non-standard cartridges. If you need to adjust your system, we have replacement weights and bumpers available here.

Questions & Answers 29
-
What would be recommended for the PSA guardsman mid length gas 16” barrel?
Rolando Mota · May 16, 2026AT3 Support Team — For a 16” mid-length 5.56 NATO rifle like the PSA Guardsman, the standard Carbine weight (3.3 oz) Armaspec Stealth Recoil Spring is highly recommended for reliable cycling with a wide variety of factory ammunition.
-
I’m planning to build a ppc in 10mm what weight would you recommend?
Nicholas Gardner · Apr 21, 2026AT3 Support Team — For your 10mm PCC build, we recommend the Armaspec SRS with the 9mm (6.4oz equivalent) weight or Big Bore (5.7oz) option—10mm's higher pressure is similar to 9mm blowback systems. Start with the 9mm weight for reliable cycling, and tune with an adjustable gas block if needed; pair it with a heavier BCG for best results.
-
Will this function on a .308 ar10 suppressed reliably?
Joseph Larsen · Jan 11, 2026AT3 Support Team — Yes, the Armaspec Stealth Recoil Spring (SRS) for AR-10 functions reliably on suppressed .308 builds with carbine buffer tubes. Its 5.7oz equivalent weight and multi-stage design reduce felt recoil and handle extra backpressure well for smoother operation. Pair it with an adjustable gas block for optimal tuning on your setup!

Which one is best to reduce recoil on a 5.56 AR-15 with a super safety unsuppressed
Ty Alexander · Jan 10, 2026AT3 Support Team — For reducing recoil on an unsuppressed 5.56 AR-15, the Armaspec Stealth Recoil Spring H1 (3.8oz equivalent) is the best choice. Its multi-stage design delivers a softer impulse than stock springs, eliminating twang while smoothing out cycling on standard carbine setups. Pair it with an H1 buffer for optimal recoil reduction and reliability, users notice the difference instantly!
