So it's not the best gas rifle you can buy, but for the money its pretty darn good! It has a decent range with the .30 gram BBs in it. One thing about it; it is a slight C02 hog, but other than that minor detail (Co2 is fairly cheap anyway) this is a good budget sniper. (If you have trouble installing the rail with the included manual, heres a tip; on the screw hole closest to the bolt, the one towards yourself when aiming, theres a small screw which you must remove with an Allen wrench before you can screw in the Picatinny rail)
