Reddit reviews Empire 10 Round Tube with Tethered Speed Cap - Smoke - 20 Pack

If you're worried about having a hopper in a mag-fed only game, but you don't want to spend a bunch of money on a mag-fed marker or conversion kit, you can do what I've done for under $20: make your own "magazines".

1. buy some 10 round tubes
   
2. Get some foam or something squishy. (I had some laying around from old packaging)
   
3. Cut a piece of foam and put it around the hole of a tube.
   
4. Duct tape all the way around the foam.
   
5. Layer with duct tape until it fits snugly in the feedneck
   
6. Repeat 3-5 for all tubes
   
7. Fill tubes with paintballs
   
   I've used these in my 98's a few times and it really is a lot of fun. It takes a bit longer to reload than actual magazines, and it is on the top of your gun, but it does make it easy to see how many rounds you have left.
