well, got my new specops mounted a short time ago and blasted a few shells and everything was fine.

get out hunting today and shoot at a rabbit and go to chamber another shell. hmmmm....shell wont come out of the magazine. :confused:

ive just been looking at it and the problem is the one piece on the opposite side of the ejection port that you push to the side when you are disasembling the gun isnt moving over so another shell can come out of the mag.

ive cleaned and reoiled but it still doesnt work....any ideas?

EDIT: SOLUTION:

the knoxx forend is too short inside so i put a piece of plastic tie (1/8"?) between where the rails are attached to the tube inside the mag and the forend. the shells now come out of the mag every time like before. im sending knoxx an email about this to see what they will do about it because i dont want this to fail when i am in the middle of the bush.

I've had the same problem. If i used winchester (dry lock i think)shells they woudln't come out of the tube but when I use Federal shells from walmart they come out every time. If anyone knwos a solution i would like to know too :)
 
I take it you mean the shell catch. Can you move it with your finger? It's a piece of spring steel fastened on the end towards the muzzle. Is there a piece of crude stuck under it?
There should actually be two of them, one on the other side as well.
 
It's probably going to be a problem with the 2 arms that connect to the forearm to move the bolt back and forth. Take your gun apart and bend them out/apart a little. If it's not a problem with the 2 arms, it's a problem with the shell release being twisted in where the arm his to push it into the receiver.

Are you sure there's nothing stopping the action from being pumped all the way back? Cause that shell latch don't release till the very end of the stroke.

Also take out the trigger assembly and watch what's going on with the releases as you slowly pump the action.

express super mag to be exact.

only thing ive changed is i put on a specops stock and knoxx forend. could i have somehow messed something up when i installed these?

ive taken my gun apart at least 50 times and this has neevr happened before...now i have the knoxx and it does this. maybe just a coinscidence?

Try to put the old stock back on and see.
Perhaps the bolt from the new stock is a tad too long and protrudes inside the receiver just enough to block something...
Good luck!

My next step would be to spray or wash out the inside of the receiver in the area of the shell latches; be careful, since you don't want to put enough pressure on the latches to pop them out (and they're a PITA to have staked back in). There are notches in the action bars that run back off the pump that are supposed to control exactly when each latch is cammed out of the way, and short of having some sort of gunk wedged under one of the latches, or having one of them already ready to pop out, there isn't really a lot that can go wrong with the system.

I had a similiar problem with the wilson combat I put on my 870 as well.
I had to play with the spacing of the two arms (pull them out a bit to get the same parallel spacing as the stock..

that and when the stock was all the way "back" towards the receiver, I had to grind off a bit as well.. you just and to play with it a bit.
