Hunting optic for Hatsan 125 Vortex Sniper

I have a ATN X -Sight on my Mrod .25 and i'ts awesome, but the setup is a bit heavy for woods walking/stalking. I'm looking for something that can handle close to 50 yard range on small game while on the move, mounted on a magnum air rifle. I've broken 4 scopes rated for air guns on my Crossman Nitro Venom already.I have a Hatsan 125 vortex sniper .25 on the way so you can see why I'm scepticle to even think anything can stand up to i'ts recoil for more than a few K shots. Would love to know I'f there is a no BS low cost durable scope or dot sight, under 120 , that wont break after the first tin of shots.
 
I have the hatsan 135 in .177 and i got the hawke sidewinder 30 3-12-50 and i recon its very nice. I was getting about a 10mm group of 5 at 10mts with h+n barracudas 10.65grans. But it died tonight😢. I have only had it about 3weeks. When i had a shot it went all out of focus n it seems to me to have something to do with the magnification as when you change the magnification it will focus but take a nuva shot n its out of wack again. Ill send it of tomorrow and see what they say.
