Severe barrel droop in Gamo Swarm Fusion Gen 2 - need fix for Hammers 4x12 scope

My Gamo Swarm Fusion Gen 2 has barrel droop causing shots to be 10" or more low at 25 yards. Iron Sights when adjusted give 1" or less grouping on center of target. I have tried 3 scopes and none adjust enough. My Hammers 4x12 is long and has difficulty even fitting behind magazine/break. Might have to stick with stock Gamo or other smaller scope, but they all can't adjust enough for droop. Would I be better served with Sportsmatch .75mm one piece droop mount with arrestor pin or FX No Limit rings that do not come with arrrestor pin? Would the .75mm compensate for 10"+ low shots? All scopes give great groupings, just all well below target.
 
You could always study up on barrel bending and do it yourself or maybe find a fellow meber that lives close and would be willing to help, but the minute you do, Gamo very likely voids the warranty because you tampered with the rifle.
Adjustable rings or a drooper base, ok, but either is just a bandaid to a bigger issue, which is manufacturing defects and your warranty definitely covers that. I'll stick with getting Gamo to send you a new rifle to replace your defective one.
 
I got it on June 15th, and put about 300 shots through with iron sights to break it in. Mounted 3 different scopes and all can't be adjusted enough for barrel droop. I contacted Gamo to see if I can swap it out, but would use adjustable mount if that solved problem.
Ya, butttt.... Id see what they say or maybe if not to late try the retailer as steve said. Best i know gamo aint know for droop issues , but you never know. You just don't see it common like a diana/ rws . Also if gamo will rma/ exchange it and your in / under the first year of warentee gamo foots the shipping bill both ways.. so be sure to get a printable shipping label from gamo to send it back.. (fyi).
 
Thanks for all the suggestions. I hope they'll swap it out, I already had them replace the loading mechanism that stopped working the first week. They shipped it to me to have me put it in myself and no issues hundreds of rounds later. The rifle itself shoots really well. Did a 15 shot grouping at 25 yards today with a 1" spread total using iron sights and an artillery hold on a rest. Since I got it for destructive pest control, I might do the bandaid of adjustable sights if they won't replace (and Amazon was seller and its past returnable date with them) but even iron sights will work well for its intended use.
 
I dont have auto loader gamo but i just use open sight on it.. i prefer open over scoped on all my stuff.

Now mine has the old loose flip floppy rear blade i had to " fix" to keep it tight and true and still adjustable..

Dont know how you pulled off gamo sending you a part . Thats super out of the ordinary. Like a one in a million .

They would not send me a new updated rear sight blade or anything else ive asked for or needed . Its you need a ffl. Or its send it in "period"! Not the sight , seal, screw, baffle, nothing in any of my ownerships . Nothing.

Maybe they changed there policy from a few months ago? Thats a rarity for sure. Good for you anyway...👍

Anyway the open sights are good and true to 100y once your good and broken in . You may find scoping a waste of time and good money..lol.

Enjoy.
