Armaspec SRS-AR10 Gen 4 AR-10 6-Position Buffer Tube Kit - Black

The Armaspec SRS-AR10 Gen 4 Buffer Tube Kit is a complete drop-in upgrade for the AR-10 platform, combining a Mil-Spec 7075-T6 aluminum 6-position buffer tube with Armaspec's signature Stealth Recoil Spring (SRS) system. The included tube accepts any Mil-Spec stock assembly and provides six positions of length-of-pull adjustment, while the steel castle nut and end plate deliver a secure, mil-spec-correct mount to your lower receiver.

At the heart of the kit is the SRS Gen 4 enhanced multi-stage recoil spring, designed as a direct replacement for the standard AR-10 buffer and spring. The multi-stage design reduces felt recoil and keeps the spring from rubbing against the inner wall of the buffer tube, resulting in a quieter, softer-shooting rifle with less wear on internal components.

Finished in matte black, this kit is a straightforward way to upgrade an AR-10 lower with a matched tube, castle nut, end plate, and recoil system in a single package. Compatible with standard AR-10 carbines using a Mil-Spec pattern buffer tube.

Kit Includes:

• Mil-Spec 7075-T6 6-position buffer tube (matte black)
• Steel castle nut
• Steel end plate
• SRS Gen 4 enhanced multi-stage recoil spring
