Dynamic recoil buffer and buffer spring has been designed to work together as a set. Dynamic recoil buffer spring is working with a normal buffer, but we encourage you to use as a set.
1. Disassemble an upper and lower receiver, and take spring guide holder part. You can use an advantage of leverage with a thin wrench.
2. At this point, you need to watch out if the buffer already installed in a stock tube in popping out.
3. Remove the old buffer and spring, and install the dynamic recoil buffer set.
4. Put the spring guide holder back, and assemble the upper and lower receiver together.
