How To: Install Your Magazine Tube Extension On Your KS7

This Magazine Tube Extension for the KS7 extends the magazine capacity by 3 when using 3” shells or by 4 when using 2 3/4″ shells.


Your magazine tube extension kit will come with the extension itself, a fancy aluminum follower and a much longer spring. 

Make sure your gun is clear and your safety glasses are on. 

Step 1. Remove the cap. If you need to use a tool, you can use a pair of pliers or any other household tool. 

Step 2. Remove the spring.

Step 3. If you want to use the new fancy aluminum follower, dump out your stock follower (plastic white). Drop the aluminum follower in with the small side facing the chamber. The end of your spring will fit right inside the follower so make sure to drop it down so that side is exposed. 

Step 4. Next, you want to take your extension and screw it on. 

Step 5. Take the spring and slide it onto the follower. Take two fingers and grab two or three coils at a time and feed them in. 

Step 6. Lastly, grab your cap and while holding the springs in, let the cap catch the end of the spring and then go ahead and thread it. 


That’s it! Your Magazine Tube Extension on your KS7. Take it out to the range and have some fun!
