I am looking at one of these optics for my 18 inch AR-15. I'm torn between theses two scopes Vortex PST 3 - 15 x 44 FFP: https://vortexoptics.com/vortex-viper-pst-gen-2-3-15x44-ffp-riflescope.html?vortex_reticle=22 Primary Arms DMR 55.6 ACSS 3 - 18 X 44 FFP: https://www.primaryarms.com/primary...pe-gen-3-illuminated-acss-hud-dmr-308-reticle I can't decide, the Vortex seems like a nicer optic. I see quite a bit of claims under the Vortex warranty on sending them in for repairs. I even see a few of my followed youtube channels having a problem with the optics, but in the end the optic was fixed. The Vortex seems like the premium optic, but the video and reviews on their website. I see a lot of claims on warranty work. The primary Arms seems cheap, but I hardly see any negative reviews. I have the Primary Raptor on another optic and I love the redicle. I see less problems with primary arms optics vs Vortex. But that also depends on the amount of sales too. I see nothing but positive reviews on Primary arms optics So in summery, I like the glass of the vortex but worried about the quality. I really don't want to spend the something to send in for a replacement. I prefer the redicle (ACSS) redical on the Primary Arms, but I am worried about it being too cheap going on a nice rifle. What route would you guys go? I would like to hear any input.
