Great for the money - Tasco Red Dot 1x30mm 5 MOA Matte Rifle Scope BKRD3022 Tasco 1x30

I've used this sight for over three years on my Ruger 22/45 Target pistol and it's been perfect.
I bought this one because of the Tasco name and the low price and have not been disappointed.
It fits perfectly on the Weaver mount that came with the pistol. Easy to zero. Battery life is great.
You don't have to think about it like with a scope, you just keep both eyes open and put the dot where you want the bullet to go.
I usually only need to set the dot on 1 or 2 and it gets incredibly bright at 11.

I'm careful with the sight, don't knock it around and it has been plenty rugged enough.
