Armaspec AR-15 Multi-Stage Stealth Recoil Spring 9mm/6.4 oz- Carbine Length

The Stealth Recoil Spring (SRS) 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.

Features:

• Drop-in replacement for standard buffer and spring
• Reduce felt recoil
• Keep the buffer spring from rubbing against the inner wall of the buffer tube
• Buffer mass is designed to stay under constant tension against the bolt carrier
• Rubber O-ring on the head of the buffer mass prevents metal on metal contact
• Made in the U.S.A.

Specifications:

• Equivalent Weight: 6.4 oz.
• Actual Weight – Complete System: 9.3 oz.
• Compatible with AR-15 with carbine-length buffer tube.
• Length: 7.18″

Manufacturer Notes:

• The SRS comes with Red LOCTITE on the front metal stop and Blue LOCTITE for the bottom bumper, when reassembling we recommend reapplying LOCTITE. The SRS 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.
• 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.
