Armaspec’s Stealth Recoil Spring, currently in its fourth generation, is a self-contained upgrade to the AR-15’s standard buffer and spring—and the company now offers the unit as a kit that includes a trio of interchangeable buffer weights that allow the user to tune it to his or her rifle/load.
The SRS runs more quietly than the traditional buffer assembly—as the buffer spring no longer scrapes along the inner wall of the receiver extension tube during the cycling of the bolt—and a two-stage spring design provides better recoil absorption than the original setup.
The kit comes assembled with a 3.3-oz. carbine weight attached, but H (3.8 ozs.) and H2 (4.7 ozs.) weights are also included and can be installed in only a minute or two.
Suggested retail price is $82. For more information, visit armaspec.com.
