Remove the factory base pad.
Remove the screw and washer from the magazine extension and set aside. If the model of magazine extension you have came with a replacement spring, remove the factory follower from the spring and install it on the new provided spring in the same direction it was on the factory spring.
Inspect the inside of the magazine tube for excess material or debris, there must be a smooth transition from the magazine tube to the extension.
Insert the spring ensuring that the follower is facing the correct direction.
Compress the spring into the magazine tube and while holding the spring below the ﬂange of the magazine with one thumb slide the Warne magazine extension onto the ﬂange at the bottom of the magazine.
