Hornet Maxxim Barrel Lock
« on: January 24, 2019, 02:12:34 PM »
Hi all,

I was getting ready to shoot yesterday and I noticed a slight rocking up/down.

Are there any known issues with these rifles?

Thanks.

Okay.  After some additional investigation, it seems that the problem is that the barrel locking pin sits in a plastic sleeve below the breech.  It engages against a pin below the transfer port.

The locking pin has worn out the plastic sleeve and now the barrel is allowed to rock up and down.

You will have to replace it. If you do it with steel them maybe the steel will wear the detente wedge or whatever it has. Just more Gamo.

So many good things about this rifle.  Too bad a dumb design is killing this rifle early.

I thought they only dealt with FFL types.

I sure hope you get it resolved. I picked up one of those rifles for 60 bucks the other day.

I returned the rifle.

Look at where the lock-pin sits under the breech.  That plastic wallered out after maybe 800 pellets.


Someone with resources could drill and sleeve it. Or maybe shim it as the plastic wears.

Best of luck...

Xipital,
Oh, I see you returned the rifle.  Good move. 
This is a known problem and there is a decent fix for the up and down wobble.  It's even ok that the plastic detent wedge is "wallered out" (great term!) and loose in its socket, like mine is, too.  I cut a piece of K&S brass tubing from a hobby shop to fit over the detent bar to thicken it.  Choose a diameter tubing that will fit tightly over the bar, cut the tube to length, then cut a space out of the side of the tube so it can snap over the bar side-on and stay.  I got this idea from someone else here in this forum.  With a thicker detent bar, the wedge pushes harder against the bar and forces the detent pin hard against the side of its socket, which reduces the up and down slop.  I did this last year and my Gamo may have two tubes over the bar, I can't remember.  I hope this helps others with the same problem.
