I have shot Axcel sights for years. I have a 5 and 7 pin.
I am really impressed with the sight so far and never thought that I would go back to a multi pin sight after using an HHA OL XL TX-5500 single pin. But the sight is very well made and I like how I can move the bubble level to the top of it. Plus the sight pins micro adjustment on the Axcel sight is great. No wiggling around while moving them up or down while sighting in. Definitely happy with this upgrade!
