Add To:

The Stealth Recoil Spring™ SRS ™ is a self-contained multi-stage drop-in replacement for your standard buffer and spring. The Stealth Recoil Spring ™ is designed to reduce felt recoil as well as keep the buffer spring from rubbing against the inner wall of the buffer tube. The buffer mass is designed to stay under constant tension against the bolt carrier and the O-ring on the head of the buffer mass prevents metal on metal contact.

Armaspec recommends using Red LOCTITE for the front metal stop and Blue LOCTITE for the bottom bumper. The Stealth recoil spring can be installed with or without a buffer retainer. The polymer bumper goes towards the rear of the firearm and the weight mass with the o-ring goes towards the bolt carrier.

Can this be used in an AR15 pistol build?
Saeed T on Sep 19, 2018
I have a PSA 10.5" ar pistol, will the armaspec srs H2 work with it?
Lee W on Jan 30, 2019
BEST ANSWER: It should work great! I have one in a 300 Blackout and love it! Whether I am shooting sub-sonic ammo or super-sonic hunting loads it cycles great and is way quieter that a standard buffer spring! Great product. I will definitely be buying more of these for other AR's.
Is this product complete and ready to use, or do i need red and blue Loctite's for it to function?
derick L on Nov 14, 2018
BEST ANSWER: I don’t know what you would use loctite on. It just replaces the buffer spring and buffer. All you need is some oil or grease, whatever your preference.
Will this work on a 6. 5 Creedmoor gen2?

Easy to install. Arrived quick and seems to be very high quality. I also purchased the spacer for full stocks. Hope to try it out as well on another gun.

Great for suppressed 300 Blackout
Great for my suppressed 300 Blackout pistol AR shooting heavy subsonics. Reduced the "sproing" noise of the buffer spring to nothing.

Good, but could be better.
Does what it says it does. Unfortunately they designed it with an o-ring that sits between the unit and the end of the bolt carrier. Bolt carrier slams into it, and will destroy the oring over time

Great product at a great price.
This product works as advertised to quiet the reverberation associated with a standard spring and buffer setup. It also assures consistent cycling by removing the variability inherent to the legacy system. This is a must have upgrade for non-reciprocating side charging AR15 uppers and anyone trying to optimize a 300 blackout build for subsonic and suppressed operation.

Quiet And Smooth
The two-stage design is welcomed.
I tore it down and lightly greased it with Energy Release G-200 after stripping the factory lube off chemically, and it seems to work as advertised.
It is slightly to moderately overpriced, and that squishy soft brown o-ring supplied is too soft to last more than 100 rounds without signs of disintegration (I'll try Highly Saturated Nitrile for the next 100 as a test).
I highly recommend the retention of the buffer tube catch and spring (although it makes disassembly slightly more difficult).

Great for the money! I’m never gonna but a regular buffer spring again!
Amazing!! If you do anything extra to your AR-15 or AR-10, buy this part!! It makes a world of difference! Never not getting this part.
