I have an AR with a red dot on it, but want something more practical for SHTF. I've come to the conclusion that a prism scope would be a good option, due to the fact that batteries are not required for operation, they have minimal moving parts, and the low magnification makes target ID at longer ranges easier. I was thinking 3x would be a good choice, but I'm open to suggestions. I've narrowed it down to a few options an was wondering if anyone here has experience with any of these optics. Sightmark Wolfhound 3x Primary Arms SlxP3 SIG Bravo 3 Vortex Spitfire 3x Burris AR-332 Crimson Trace 3.5x Athlon PR31 I'm skewed towards the vortex, primary arms, and sightmark options, the former two due to their popularity, and the latter due to my good experiences with other sightmark products. Of course there are other offerings from steiner and trijicon, but these are out of my price range.
