I have a Vortex Sparc. The no nonsense warranty sold me. I got a friend a primary arms for his SKS. Ive shot both and without any bias, id say the Vortex Sparc has a slight lead. One thing i DO NOT like is the on/off position on the Sparc. Its on the side and after reading reviews about how putting the gun in a case could accidentally turn the dot on, thought it wouldnt happen to me. I was wrong. It did happen and the negative reviews on the on/off position hold true. Other than that...no complaints.
