I know they can. There are definately some hpa guns out there. I can also tell you that the pressure that comes out has to be low. Anything like the condor with lots of high pressure fast air just blows up the paintball. But there are guns that’ll do it. Adam can tell you more, he used to play paintball.
Most off the shelf paintball guns run at 850 psi. that is what all co2 bottles and most hpa tanks have the reg set at from the factory. Some of the higher end paintball guns run off of low psi like 400 or so, so they have special order regs for them.
