Tippmann m4 feeding problems
 

Anyone know the tippmann internally very well? I just changed out my stock barrel to a MB 6.03 tbb.....everything seems to line up perfect and went back together no problem.

My bbs will not feed and are falling out of the hop up unit. Im getting a good flow of air out of the end of the gun, no air seal issues......anyone have a solution for me?

did you lose the nub in the hop up unit?

No idea, the hop up is so different then your normal aeg hop up. I mean you cant even get to the nub if there even is one. Supposedly a allen hex screw adjusts your hop up but im not sure how as its on a angle and not where the window is. Messed up hop up unit :(

This might help you out, or check out the Tippmann fb group. Lots of good info over there.
