Also just my own personal pet peeve much like guys saying they are going to an "airsoft war" for whatever reason guys referring to bolt action rifles as a "sniper" rather than a "sniper rifle" just rubs me raw. Nearly as much as guys calling a desert eagle a "deagle" or other things along those lines. The sniper is the guy behind the rifle not the rifle itself. And even further in airsoft while we might be snipers it's pretty loose terms for the capability we've actually got even with the best guns upgraded and ready to go.
Like mentioned above most bolt guns take allot of upgrades to get to a decent level, and a heck of allot of time. Upgrading airsoft guns to shoot more accurately is in my opinion often more about time then money but both play a role. We're going to need to know what rifle it is though or we won't have a clue, right now we don't know if it's spring, gas, HPA etc. Now what brand it is, all the parts vary gun to gun and what needs to be upgraded.
