My mate has a Gammo .22 has had it couple years. It's forever throwing springs it's good from while and accuate. Then it goes like a women with a credit card . He's getting to the stage now after taking it back to the dealer and replacing springs where hes going to through it on the ground.

So was wondering do they make an after markert spring that will stand up and perform constant ?

Since I can only guess.......what spring and what do you mean "throwing". I have a Gamo Hunter 220 pellet rifle that I shoot all the time and it doesn't throw anything.
