Browning X-bolt 308W 9 rounds magazine

This magazine is made to hold 9 rounds of 308 win cartridges. The spring used is an AR15 30-RD MAG SPRING MIL-STD (SS) EA which is cut to 120 millimeters to fit. The spring for the magazine catch is from an ink pen. and the pin for the catch is 1.5 millimeters of welding wire which is 21 millimeters long.

I have used the magazine in its current design so it works.
