Proto matrix rail, 14" proto barrel, VL evolution 3, crossfire 68/4500
No upgrades, jams up
First, the good. This loader is pretty cheap, I bought mine for about $60 on eBay. It feeds pretty fast too. I set my PMR on 20 bps with the eyes off and it never chopped paint. Also, because it has soft spin paddles in it I don't think I've ever had a paintball break in the hopper that I can remember. The battery life is also good. I think I may have changed the batteries in in twice since I've had it. Now for the bad. First, its pretty ugly but I've gotten used to it by now. There aren't any upgrades for this except the z-board which came stock on mine, but you can buy it without it. Mine seems to jam up alot too. When I try to un-jam it during a game, I always cut myself on the edge of the lid and now I have a scar on the side of my thumb from un-naming it so many times.
