Great starter red/green dot - Leapers UTG 4.2in ITA Red/Green CQB Dot w/ QD Mount, Riser Adaptor

Bought this to try out how I would like a red/green dot sight. Have used red dots sparingly in the past but not enough to really "know" how to use one. So I got these as the price was cheap enough that if I did not like it, I wouldn't feel like I just wasted a ton of money. Since using these, I have really learned to appreciate the red dot sight. Once I figured out how to line up the red dot with my iron sights, they are right on at 25 yards. I have yet to get out to the outdoor range to try them out at longer distances. But I mainly set up my AR15 for close quarters engagement, so 25 yards is good enough for now. I can see how a quick target acquisition is made easy by the red dot as it makes it easy to just point and shoot. The quality of the UTG is great especially for the price. Everything feels tight and sealed, easy to figure out, and easy to adjust. It comes with the allen wrenches for mounting and sight adjustment and batteries. There are only two cons about this: (1) it is bigger and heavier than I expected, but it's still fits well on the AR. I did have to buy a bigger carrying case to transport my AR with this sight mounted (2) the adjustment knobs require an allen wrench (provided) to lock them in place. So you have to have it nearby if you need to adjust the sights. But since I have a Magpul grip with the storage, I can carry the allen wrenches and extra battery. But since I've set and locked the sights, I have not had to adjust them again. Overall, I am very satisfied with the UTG red dot sight especially for the price. You really get a quality red/green dot sight for the price.
