I’m looking to get a paintball gun for tactical play, The gun is a Smart Parts EOS which runs on 280 PSI I noticed that some other guns ran from150 – 200 psi so I don’t know wheather 280 PSI is good or not is it Good?

It does not make your gun more accurate, that depends all on barrel, the gun itself, and the person shooting.

All the PSI rating does is typically show how air efficient it is, the lower the PSI the more shots you will get typically.

Whatever gun you pick IF it is electronic DO NOT use Co2 in the gun, use HPA. Although it says you can use anti-siphon Co2, don’t. At high rates of fire or over a period of time it will ruin the solenoid, board, etc.
