Nixon Posted March 29 Share Posted March 29 What battery are you using? 11.1? If so try it on a 7.4 and see if the problem goes away. Link to comment Share on other sites More sharing options...
Jay246 Posted March 29 Author Share Posted March 29 I'm using 7.4s so don't think it's that Link to comment Share on other sites More sharing options...
Shamal Posted March 30 Share Posted March 30 So you say it's got a newish max hop unit,rubber and new inner barrell. Was the gat working properly before these changes? If the double feeding happened after, then it points to the hop unit. I can't offer any possible remedy but I would start looking there.

Start by taking the Maxx hop unit out and refitting the original unit. If it feeds normally, which I suspect it will, you have found the problem. If it doesn't, do the same with the other parts you have changed until you identify the problem. Maxx hop units are notoriously finicky about which guns they will work in.

That did not seem to be the case based on your original post: "Hi guys iv got an ICS split gearbox M4 with newish maxx hop unit new hop rubber and new internal barrell and it's now double feeding..." When you say "double feeding", what do you actually mean? Is it pushing out two BBs at the same time or is it cycling twice, giving two separate shots. If the former: If your sector gear has a delayer chip, take it off and see if that makes a difference. If that does not work, one thing you could try is to use a 4mm drill to make a small indentation in the "roof" of the hop unit, directly above the feed tube. This seems to help prevent double feeding by giving the BB somewhere to sit rather than trying to follow its friend through the hop lips. If the latter: Try fitting an Auto Braking mosfet.

Pseudotectonic Posted April 3 Share Posted April 3 Your entire outer barrel is dipping down because the barrel nut is probably not solid enough, try this to align the whole assembly so your hop unit is coaxial to the nozzle so it chooches properly But the real culprit is your new hob rubber Link to comment Share on other sites More sharing options...
