Double Feeding Issues TR16 A2

[Just_Jack 1991]

hello,

i know this has been covered a fair few times but its just a quick question, so i had upgraded my gun internals to a ProWin hop up unit and a MadBull Shark type hop up rubber with a H type nub.

performed alright throughout the day, didnt need to change the hop up after i had it set, at the end of the day (last match) it just started double feeding, i had probably had about 2,500 bb's through it and then no matter what i did it would not stop double feeding, im guessing its an internal issue but as i have never had to deal with double feeding before i dont know the most common causes.

any help would be greatly appriciated

Based on what you changed I would guess its the lip of the hop rubber, the BBs aren't getting held at the lip. Remove the hop unit + inner barrel and put a BB in their on its own, it should be held at the lip. It might be getting let through a bit too easily, its a common cause of double feed issues on hop unit or rubber upgrades especially considering they all have slightly different tolerances. The prowin is a little odd in dimensions and I think its one of the reason people recommend the Prometheus purple with it.
