All it does is measure the speed of the projectile being shot through it, hell you could use a paintball chrono to measure how fast you can throw a pen or rock through it if you were so inclined to do that.
Cool thx. ill look at buying a m110 spring. what else sould i look at for increasing durability? is the garder gear set worth it? oh and for cqp (mp5) limit is 300. so an m90 spring should be good?
