SRC G36 feeding issue

[Hortons Heros]

Looking for anyones experience with something like this.

SRC gen 3 I believe. The BBs are feeding fine into the hop-up unit from the mag but once there they are jamming where the inner barrel meets the unit as far as I can tell. When this happens the cylinder still has air in it and is causing the piston to not go all the way forward and the gears are catching at the wrong point and wearing it down.

Sometimes it will feed an entire mag or two no issue but it always jams at some point.

Hop-up unit is metal but I can't see any burs or lips that it would get caught on. Hop-up is all the way off and I have pulled the whole unit out and fed bbs into it and I can't get it to jam until I have it all put back together.

All of this happened I did a spring swap but I did not work on the hop-up unit. It looked like a gear box issue at first but I can run the box for a long time on it's own and no problems.

Try on an other hop-up rubber.

Sounds like the new spring might put more stress on the cheap rubber that is in there and caused it to tear a tiny bit.

I had similar issue with mine and changed for Guarder clear. It worked perfectly after.

that is the odd thing. I down graded the spring by 50fps.

Hmm...

Might be that the problem was there already and the lower air pressure caused misfeeds...

This seems to have fixed it,

Noticed that the hop up rubber was folded down a bit rite where the nozzle would slide against it. Changed the rubber and put 400 bbs through with no issue.

Bad BB's I has an issue with mag feeds and i switched BB brands.. I oiled the mag spring too. Maybe there is too much silicone oil in the hop up?



Disregard..

Cheers..

The owner was definatly using some low quality BBs. They jammed his MP5 and now they jammed the G36, if it happens again I am just going to skip working on it until he buys some now BBs.
