Hi-Capa Slide Problem

delta76 · March 19th, 2009, 00:25

I have a WE Hi-capa, for some reason when firing the slide gets caught on the way back, it seems to be caught on the hammer and requires significant effort to get it unjammed. I don't think it's a problem with the recoil spring because when actioning the slide by hand it functions perfectly, sliding back into place on its own without catching or sticking it only sticks when firing. Could this be an issue with the lubing of the rails or something more serious? I can't see any broken or cracked components.

this might be a really dumb question but...

do you have BBs in the mag?

delta76 · March 19th, 2009, 00:41

LOL yeah mag is loaded, it's not getting stuck at the very back of the action but on its way back and jammed is the keyword it wont move unless I pull it back very hard to release the jam.

Your blowback unit gets caught on the hammer. Try shaving some parts on the hammer. File it down a bit.

If your blowback unit is getting caught, then it would also get caught when racking by hand.

But that's not the case.

It actually sounds like you might be catching the slide on the chamber cover...

does the slide cycle properly if you're lightly pushing the barrel back?

What do you mean by pushing the barrel back? I'm a little confused by that.

ILLusion · March 19th, 2009, 01:22

Push the muzzle towards the rear of the gun, so that in essence, you are assisting the slide in pulling it backwards. Do not push it back so far that it comes out of battery, or you will not be able to fire. AND MAKE SURE IT'S NOT LOADED WHEN YOU DO THIS!

When I dry fire the gun the slide only moves back and locks into position with the slide catch, it doesn't complete a full cycle.

I had the same issue with my WE Hi-Capa. It seems to be a common problem with these GBB's. I think I read somewhere that it was an issue with the magazine not fully sealing with the feeding nozzle (could be the o-ring). I'm just hoping I don't encounter the same issue with my P14. Though your issue seems more serious so, maybe your loading nozzile is torn or something.

Whether or not the issue is the loading nozzle, I'm pretty sure that the sticking is caused by the slide getting jammed on the chamber cover, but why does this only happen when firing??

Try lubing the contact points between the hop unit and the chamber. When the action between these two parts are sluggish due to extra weight, [metal chamber/silencer/compensator] the chamber gets caught on the slide and jams it.
If lubing does not work a bit of filing on some places to make the action smoother can be a cure.

Sometimes happens when steel chambers are installed on TM hicapas.

lubing the hop-up and chamber did the trick! never would have thought that was the problem until I saw the massive wear marks on the hop-up! Learn something everyday, thanks a lot everyone.

Like I said, the problem is occurring because the outer barrel is not being pulled back far enough. If there is too much restriction, the movement could be too slow and the slide will catch the outer barrel before it's even reached it's rearmost (tilt) position.

Lubing it solves it in the majority of these cases.

This problem is why I suggested dry firing while manually assisting the outer barrel to its rearmost position to see if that resolves the issue. If it does, then you can identify this problem right away.
