I got a red dot for my 4095. The Sparc is back on the AR, where it lives. So I went to the local range to get the red dot hitting the target. Finally got it sighted in at 25 yds, (longest distance there, outdoor range a no go due to snow and ice). The guy next to me showed great interest in the carbine. He has a couple of nice pistols he was shooting. I was ready to go, but asked him if he would like to shoot it. A big Yes! for an answer. Loaded up 10 rounds of .40 and turned him loose. He put a target out about 15 yds, and put the last 4 shots right around the center of the target, shooting offhand. He really liked the carbine, and the way it shot. It appears I got the red dot about right. He said he is planning on getting one. A lot easier to shoot and smack the target than with a pistol. My good deed for the day.
