I really like this product because it makes acquiring my target much faster and easier in those low light conditions. I was very impressed that it fits my Stevens Model 94c 12ga. As well as my wife's H&R single barrel 20ga. Easy on and off, no tools or glue. Great product, great price.
Bought this to add to a home defense 12 gauge, seems to be a very good and simple addition that just works. Fit is very tight and does not seem to move once on the barrel, did I mention it was simple?
I would buy another if I needed without hesitation.
Every friend that has seen how much this sight helps has since bought one for their shotguns. In low light situations it is amazing how easy it is to see that little green dot. Outdoors it glows like it has a battery in it. I used it with slugs in my Mossberg Persuader and it is a true 150 yard shooter. Works well for clays also on my 870 Wingmaster also.
Bought 2 of the green tru glow Glo-Dot II. It went on just like the instructions stated for a good tight fit, fibre optic is good to accommodate my bi-focals. Have not shot with the two barrells I put them on but do not forsee a problem with the snug fit. V grove in front allows you to align perfectly. Would recommend from what I see now.
