Now available from Keepshooting.com is the G3 buffer pin, an integral element of the buffer assembly. In addition to the buffer pin, we have several other parts available for the G3 buffer assembly, including the G3 buffer spring with more coming soon.

In machinery, in this case firearms, a pin is a component of the machine whose purpose is to secure two or more parts together, relative to each other. The G3 buffer pin is a pin that is housed in the buffer casing. Its purpose is to secure the buffer spring inside the casing, which is attached at the rifle’s back plate/butt stock.

Without this pin, the buffer will be inoperable, as the buffer spring will be insecure. Ensure an operational buffer with a pair of G3 buffer pins for only $2.50.
