The AR's are very good yote guns and about the only complaint you'll see on them is their weight. They handle well, are accurate, use a good cartridge and have fast follow up shot capabilities without losing sight picture. The gunsite on the other hand is a horrid choice. Absolutely none of the features it has over traditional bolt actions are a benefit in the field and the .308 will kill em deader than needed. Excessive recoil for the job, excessive damage, unneeded features.
1- 10 scale? AR = 9 (only because nothing is ever a 10), traditional bolt action in appropriate caliber = 8, Gunsite Scout = 2.
