This is the current buffer used in the M107A1. If you own an older M107A1, this kit will upgrade the rifle to accept the most recent buffer. This hydraulic buffer was designed in order to assist with dwell time, suppressed fire, and assisting in mitigating recoil slightly.
A new recoil main spring is not required.

*Can also be used in Model 82A1s. The 82A1 is not designed to be shot suppressed and this buffer would only be used to help mitigate recoil slightly.

Includes:

• Hydraulic Buffer Assembly
• Buffer Sleeve
