No experience with your named Red Dot sights, but lots of experience with Dot Sights. IMHO, for your AR 15 type rifle and even your 10/22, the 4 moa dot would be close to optimum. The smaller dots are good for benchrest shooting of small groups. They are harder and therefore time consuming to find when in a hurry to get a shot off. On a SD handgun, I would go for a 6 or even 8 moa dot. It would never shoot tight little groups off a bench, but would be just right when thing go 'thump in the night' within your home. .......

Please do a Range Report for us when you get a little experience with yours.............
