I have had my Hammer since August, took me a while to get my air situation straightened out but I am 100% self sufficient there now and let me say, this rifle is a riot, some questionable practices by customer service but everything I needed had been sorted out and they took care of me in the end.
Ive only shot out to 75 yards as Ive only shot about 100-125 rounds through it but I plan to take it out much more once my booster pump is in my hands.
