I just bought a Stingray SR3 laser from ARMA LASER for my Sigma. Went to the range yesterday to dial it in and had a helluva time. For the life of me I cannot get it right, I was shooting better without it. 140.00 dollars wasted?? I am hoping someone on here can give me some pointers / suggestions. I read the directions, however as far as the elevation goes the instructions are vague. I contacted Arma Laser and the only response I have received from them is "when did you buy it" havent heard back from them. Thanks
