Stealth Recoil Spring SRS AR-10 GEN4 (ARM253-AR10)

If you like your AR-10 but want it to feel smoother and less “springy,” this is the upgrade. The Stealth Recoil Spring is a self-contained, multi-stage system that replaces a standard buffer and spring with one captured assembly, built to help reduce felt recoil and quiet down the action.

What you’ll notice

• A smoother recoil cycle from the captured, multi-stage design

• Less spring noise by keeping the spring from rubbing the inside of the buffer tube

• More consistent cycling feel thanks to constant tension against the bolt carrier group

Quick specs

• Length: 7.18"

Installation and maintenance (high level)

Before installing, Armaspec recommends re-tightening screws using two 3/32 hex keys (or one 3/32 hex key with leverage), then re-tightening during routine maintenance. (armaspec.com)
