Questions & Answers
I have an Odin works Zulu 2.0 and the main rod of the spring protrudes a good .5in beyond the buffer tube. i did purchase the carbine length Expert Answer

I would highly recommend you reach out to Odin Works to trouble shoot your issue because these springs are meant specifically for carbine length buffer tubes or rifle length buffer tubes. The buffer tube on the Zulu stock is a proprietary "Intermediate Buffer Tube" which means you will likely run into a slew of issues because the Zulu also runs its own proprietary "secondary buffer system".

Amateur enthusiast by L.G.Brandon in PA, November 17, 2021
Smooth and quiet, with a slight reduction of felt recoil. Performance was as described. Used in an AR pistol. About 120 rounds through so far without a malfunction. Would definitely recommend product.

Love it, reduced spring noise by Bcoal, Verified Owner, December 20, 2022
This was my first aftermarket buffer/spring set up. Worked great for my 308 build coupled with an adjustable gas block. Noticeably reduced that buffer spring noise in the buffer tube. Can’t speak as to if it reduced recoil as it is the only buffer a...

will not work witu folding stock adapter by Austin, Verified Owner, December 8, 2020
Does cut down on the sound made by original buffer spring. Smooth charging. Easy to install, and can be used with or without buffer retainer pin ****** will not work with folding stock adapter due to the added piece for the bolt carrier group *****

Excellent upgrade for any AR platform by David, Verified Owner, February 23, 2022
This item delivers everything it claims. Reliability, smooth, quiet operation and easy installation/maintenance. The only "warning" I would provide is to ensure YOU buy the correct recoil spring for the rifle you're installing it in. These do come...

What's with all the complaining? by alibaba, Verified Owner, January 3, 2022
The stealth recoil spring is amazing. Works like a spring combo buffer should without the noise. Perfect for building a near silent suppressed hunting rifle. Do yourself a solid when using the stealth spring in your firearm. (First Thing) Take out ...

Product Info for Armaspec AR-15/AR-10 Stealth Recoil Spring

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. SRS-Carbine at about 3.3oz equivalent SRS-H at around 3.8oz equivalent SRS-H2 at around 4.7oz equivalent SRS-9 at around 5.3oz equivalent and SRS-H3 at around 5.6oz equivalent and SRS-308 5.7oz. Pat. Pend.image

COMPATIBILITY:

  • AR-15 with carbine-length buffer tube

Most bolt carriers have a rear opening of over .60″, there are a couple of bolt carriers in the market place that have a rear opening of under .60″ and will not function with the SRS.

9mm Bolt Carriers ONLY: For proper function of the SRS-9 in your 9mm rifle or pistol, the extra weight on the back of the bolt carrier needs to be removed. It is held in with a spring pin.
