I'm in need of another scope for my Wilson Combat AR. I've been looking into several scopes the 2 i'm considering are the Burris XTR3 and the Vortex Viper 5-25X50 FFP. I am leaning toward the VV I really like their new EBR-7C MRAD reticle and of course the warranty. I've had 2 1st gen PST's and both have been flawless. What say you?
