I am the proud new owner of a PS90 and after taking it to the range today, I decided I want an optic. I have heard a lot of great things about Vortex and their prices are hard to beat. I am considering a few options, so far the SPARC II, STRIKEFIRE II, & the SPITFIRE all look appealing. The SPARC II would be nice due to how compact and lightweight it is, but the SPITFIRE with 3x view would be nice as well. I also have considered the newly released VIPER and VENOM RDS. Anyone have any experience with these?
