Hello all! I just purchased a Remington 700 SPS tactical .308. Right now I have a Burris Fullfield II 3.5x-10x50 LRS on it. I'd like to get something with a bit better glass and a bit more magnification. Right now I'm looking at the Burris MTAC 4.5-14x42 for $550, the Vortex Viper HS 4-16x50 for $600 and the Nikon M308 4-16x42 for $550. I have a range near me that allows shots out to 800 yards, so I'd like something that will work out that far. I'd appreciate any info you can give me on these scopes or others you'd think would fit my situation/budget. Thank you all in advance!
