Paintball Tippmann 68 Carbine Feedneck 3D Printed. Marker/gun NOT INCLUDED. Selling in pairs of two, each will have a different size feedneck. I have tested it to work with gravity fed hoppers. Electronic ones may put too much pressure on the neck so use at your discretion. If you have any feedback to improve design please let me know after you’ve tested it out. Hardware NOT INCLUDED but you will need at least one bolt/nut to mount to the gun and one bolt/nut for hopper attachment. If the feedneck is too large to hold your hopper you can use a little tape or rubber on your hopper’s neck. Condition is "New". Shipped with USPS First Class.
