I had to replace the firing pin and it's dual spring kit the other day and finally got the Red Dot set perfectly. The range I shoot at is only 25 yards, which is fine because it's unlikely I could see, much less aim at any distance further. Anyway...I have the red dot mounted off to the right, on 45 degree rail adapter, so if/when the 995TS is canted to the left, the red dot is straight upright. The red dot is calibrated for 13 yards, and the iron sights, in stock position, is calibrated for 25 yards. With 1-2 seconds between shots, free standing, I can group at about 3" using either sight, at their calibrated distances. Now, I'm thinking that I may have did this backwards, and maybe the iron sights should be set at the closer distance, and vice versa for the red dot? Does it matter? Or should I ask, is there a preferred way? The reason I now think the iron sights should be on at a closer distance is because if I were to need this carbine at a closer HD setting, it's not like I can remove the dust caps and turn the red dot on...but on the flip-side, aiming for center mass, with either, and at either distance, I'm still only a few inches off either way, so it's technically a wash...probably overthinking it, but curious to hear the opinions of others.
