Check out the Sight Mark sights....good quality and a lot cheaper in price! Either way I would reccomend those type of sights,they work great in helping those of Us with glasses or vision issues or those that want something quick and easy to see thru....some of those sights are even small or low enough that You can still use the open sights too!I'm thinking about putting a,smaller Sightmark Sight on my Browning Buckmark Contour 5-1/2 in barrel .22LR...I can see further away great but it's the looking thru an open sight up close that screws me up and causes issues...those open halo/red dot sights are Awesome!
