I have a PSA 300 blackout with a 10.5 inch barrel. What type of spring do you recommend? Manufacturer Answer

We would recommend that you the SRS-C when running suppressed and sub-sonic ammo. If running subs only without a suppressor looks at our SMB-c for a better option.

Product Info for Armaspec AR15 Gen4 H3 Stealth Recoil Spring

The Stealth Recoil Spring is a self-contained multi-stage drop-in replacement for your standard buffer and spring. The SRS is designed to keep the buffer spring from rubbing against the inner wall of the buffer tube providing smooth, quiet operation and the second stage helps reduce the felt recoil significantly.image

NOTE: The new GEN4 version does not have the o-ring on the weight.

To eliminate any potential failure points, we changed the screw to a roll pin across the plastic end piece, and the cap is machined on the rodm replaced the snap ring with a washer.

Compatible with AR-15 with carbine-length buffer tube. AR10 version is available, please find under AR10 parts.

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.
