Through a series of unfortunate events, my hop-up arm has broken, my bucking has holes, and the plastic "barrel centering" piece on my barrel has broken. I know how to fix the first two, but I was curiouse if the plastic piece that a UTG MK96 uses to center the barrel in the hop up comes with any after-market tight bore barrels. And if not, does anyone have a spare they would be willing to send me? For the right price of course.
Well I would love for you to make me the piece, but when it broke, it completely desintegrated. And until I can think of a way to diy one, I think I'll search the interwebs for a boneyard gun, or if I'm lucky, yhr barrel unit itself.
I had a problem where the barrel was loose in my hopup chamber and I just couldn't get it centered. I took some electric tape and shimmed the barrel to stay in the center, while it held it in one place so the barrel was locked in the chamber like a rubber clamp.
It was a ring that fit around the outside of the inner barrel. It had a small peg on the in side of the ring at 12 o'clock that fit into a slot on the inner barrel. There are 2 pegs on the outside of the ring at 3 and 9 o'clock that were similar in size that fit into slots inside the hop up.
Barrel o.d. : .336"
Barrel slot width: .047"
Barrel slot depth: .016"
Hop up wall slot width: ~.079"
