TM FN 5-7 Shoots...weird
 

So I traded another pistol for this one a while ago.

Was working great, up until now.

It shoots...kinda, shooting the pistol right side up it uses 50% power but when
you shoot UPSIDE DOWN it shoots perfect.

Anyone know what's wrong?

Thanks, teck

rightside up put upward pressure on the mag... shoot perfect?

wow, it worked perfectly.

Still don't know what that means

It means your loading nozzle and magazine aren't making a proper seal. Or that your magazine isn't seating up into the gun fully. Try putting some silicon on the rubber on the top of your magazine.

Also check if your nozzle has a lot of play and movement in its housing... Not sure what else to tell you!

Good luck

means the mag isn't seating very well... could be a worn mag catch, could be swollen mag seals that aren't getting an air tight seal because of uneven mating surfaces.. too much lube oil (or lube oil in general with the wrong chemicals) could cause that. Maybe something else is broken.. you'll have to pull it apart and inspect that area along with the mag catch to see what's worn.

So I took the magazine catch out, looks worn.

Now to find a replacement!
