Do you mean FPS? If so, then it's rated at 595 FPS.
The fps of a paintball gun is usually in-between 300-400
That depends on the manufacturer. Most will go about 300 - 350 fps (from WE, KWA, ect.) while Tokyo Marui ones go about 260-280 fps
Most likely Not. 260 FPS is fairly slow. A Daisy Red Ryder fires a BB at 350 FPS.
PSI: It depends on how many times you pump the forearm. But Crosman says to never pump it more than 10 times. The 760 is rated at 625 FPS with a BB and 600 FPS with a pellet.
For 260 FPS and $70.00 get a BE XM8 off of www.airsplat.com For 330-350 FPS and about $150, get a Classic Army Sportline M-15A4 (M-16)
The legal limit is 300 feet per second. Some fields restrict this to 280 or 260 fps.
PSI is a pressure measurement. FPS is a speed measurement. It's not possible to convert between the two without a great deal of additional information (it might, for example, be possible to convert a pressure measurement in the chamber of a gun to an expected muzzle velocity of the projectile, with sufficient additional information).
Velocity = PSI x 12.1 THEN 12.1 Sq.Example 65 PSI x 12.1 Sq - 28.04 FPS
what is that? if your talking about an airsoft gun than about $100+ for a good one tht has 370 fps...but like 30 for a 220 fps one if your talking about an airsoftgun than it's about $600 with power of 260 fps, but if you want to upgrade it until 450 fps, it will cost $1000, but for the real p90 approximately it will cost around $35000-40.000.....
No, especially if it is a spring gun For anything other than a Tokyo Marui hi-capa, that is very bad.
To answer this question you would have to go back to Crosman and ask them directly. See the link below.
