Problem with M4 hop up :(
Hey guys.. So I got a SRC M4 and upon shooting it, noticed that the bbs just sort of dribble out, not going far at all. After adjusting the hop up, they go a little further, but then just dip to the ground.
I took the gun apart, and examined the hop up unit. The bucking looked dry, so I applied some silicone oil, still have the same problem though.
Should I replace the nub? The red madbull bucking just causes the bbs to get jammed (too hard).
Is there something wrong with the hop up unit or is it something else I am overlooking?
