Smart Parts Progressive Barrel
ZAP 404 Hopper
Simple to install
None that I can find
I play woods ball at a private field with plenty of sopts to wait and hide for an unsuspecting person to walk by. With my hopper in the way I had no way of aiming (yeah I know paintball guns aren't that accurate but some ability to aim never hurts). With this little piece of equipment I can sight down the side of the gun nicely.
If you're using any gun/marker that has a hopper in the way and you havea sight rail this will do the trick! This thing is well built, you could drop your marker and the ground and this thing will stay on.
