Good looking sights, many of their models are very similiar to the Viper.

I had an Extreme 100 and did not care for it at all, every dozen or so shots I had to tighten where the pin guard connected to the main body.

Maybe they have fixed that problem now tho.

Nope I don't think they have. You can't keep those things tight. My buddy has one and his dad has one and they both had problems keeping everything tight and not moving on them. Couple weeks ago at a 3d shoot my friends bubble fell off after the shot. Not a good sight for the money you spend on them IMO.

Thanks guys for the info. I went ahead and ordered a Viper Predator Hunter. I wanted a new sight for hunting but if the Predator Pro dovetail extension and block are compatible with the Hunter model , perhaps I can order it later on for use in 3D shoots.

I had a sniper and liked it, but I didn't think it was as bright as I liked it to be.
