I took my BIL's guide gun apart to relieve the loading gate, and put it back together. Everything worked fine. It didn't load as easily as mine, so I knew he would squawk, so I took it apart and thinned the spring a little.

I cannot cycle a loaded round through the gun now. As the cartridge leaves the tube, it hangs up half way out of the tube and locks everything up. This makes no sense.

What am I missing? It cycles fine without a cartridge in it, but put one in and it jambs up.

Thanks

There is a recess on the inside of the receiver that the narrow end of the gate has to sit in.
If misaligned, could cause your problem.

I'll check that tomorrow.

Thanks

Make sure the loading spring isn't in backwards.............Check the mag tube hole in the receiver for burrs.

Check the floorplate screws. Long in the front and short on the side. Maybe this can cause what is happening here.

I used a punch and bent the spring back in, while it was mounted, and now it works fine. I guess I got too much bow in it while I thinned it, and it was hanging up the shell. Works great now.

Thanks for the advice.

The gun shoots great. I borrowed it for a year while I worked up loads with it for him. I shot a buffalo, gave it back, and stopped and bought myself a GBL on the way back home to Texas from North Dakota.

The guns are just too much fun to shoot.
