Just for your peace of mind, I heard a rumor awhile back about the diamondbacks being able to withstand a spring or gas ram piston air rifle, so rather than go by internet rumors, I called Vortex and asked them to be sure. The rep said the Diamondback is springer rated, and will fall under warranty should anything happen.
So I won a bid on eBay and put one in my Benjamin 22 cal nitro piston. That’s been 3 years ago now, and still ticking along.
