My 22 pistol broke it in an hour - BSA Optics Illuminated Sights 30mm IR Dot Red, Green, Blue

Inexpensive, bright dot can be seen in bright daylight, somewhat heavy. Too bad the switch broke after putting about 100 rounds through my Ruger Mark III 22 with the scope attached. To get warranty service, you have to pay the shipping and send in a check for ten bucks for return shipping. Not worth it.
Pros: Bright dot
Cons: Poor quality switch
