Finally have my Rock River Predator Pursuit 20" bead blasted barell/hogue rubber forearm grip AR-15 flat top coming next week. Looking for a scope to top it with. It will be for Varmint hunting and somewhat range work. I'd like a long range type scope with Adj. turrets more for the Range and long distance shots when I have time to dial the turrets. Otherwise I'll be using it for calling and want some type of varmint reticle, dead hold, or mil-dot scope for quick holdover kill shots. I am considering the Vortex Viper HS LR in 4-16x44, or possibly in a 50mm obj. Any thoughts? I'm not sure I'm crazy about the 1/2 MOA elevation adjustment though. Maybe the std. Viper HS with 1/4 MOA elevation? I like the zero stop on the LR though. Kinda looking at the HS 4-16x50 FFP XLR and the Viper 4-16x50 FFP PST as well as maybe a Bushnell Elite 6500 2.5-16x42 with the DOA reticle. Was tossing around the idea of a 4.5-14x44 AO Zeiss conquest Rapid Z reticle 800 and trying to fiddle and figure out the ballistics of the holdover there. Thoughts, opinions, other reccomendations? I'd really like to keep it under the $600 mark if possible, but ya never know..... Looking for a lighter scope (22 oz and under) as I want my rig as light as I can considering I'm going with the PP for the lighter weight and this will be a field carry gun.
