NOTICE- This is only an extension that uses the stock 5 round mag body, follower, and spring.

Depress button and slide baseplate slightly off of button (mag extension does not require a baseplate).

Carefully slide baseplate completely off of magazine while keeping spring under compression.

Remove spring. Newer mags have a shorter 7 coil spring which will need to be replaced with our 10 coil mag spring.

NOTICE- due to magazine spec inconsistencies, make sure brass passes through the bottom of magazine.

If there are fit issues with the rounds, we lightly filed and sanded magazine ribs till round passed smoothly.

Place one side of extension onto the magazine flange.

Insert spring making sure to check proper placement of spring onto follower.

Place other side of extension on and screw together.

Enjoy!!!!
