Circle dot review - UTG Pro 3.8in ITA Red/Green Circle Dot Sight w/Integral QD Mount

Purchase this as an inexpensive way to help aging eyes. Mounted this on a Ruger Blackhawk 357. Improved my accuracy considerably when beyond 25 yds. Mounted it on my M1 carbine with a UTG bracket for the M1. That showed a considerable improvement over the iron peep sights at all ranges especially the longer ones. Left it on the M1 and will purchase another for the revolver. Have several other red dots....this circle and dot combo work much better for my senior citizen eyes. The quick release is nice but I still used the supplied Allen wrench to tighten it up a little further, as I don't plan on removing it after each use
