[QUOTE="JGRJR, post: 2370750, member: 69912"] My two cents. Build the rifle yourself. Build it around a custom barrel from Craddock Precision with a head spaced bolt. The barrel will take you a while to get. Avoid a rifle on a proprietary AR platform. Large frame ARs are not standardized like the small frame AR platform. Some uppers will not work with some lowers. Do your research. I would go DI. What follows only applies to AR platform rifles. Not rifles developed from the ground up for a piston. I have several piston ARs. So I am not negative to piston AR systems. As mentioned above there are advantages when suppressed, when operating in water and other pluses. However the AR platformed was designed as DI. This allows the BCG to move straight back in the receiver. All piston systems have a piston hitting the BCG on the perimeter. This creates tilt in the receiver. Some piston AR systems are better at compensating for this problem. Now in practical use it does not make much difference. So for hunters it is not a factor. After 10k plus rounds it might make a difference. Look at this report from a Las Vegas range that caters to yahoo’s who want to shoot. Piston ARs do not last long for them and the piston system that does the best is HK. Consider this information is for the AR15 not an AR 10. Still it seems compelling.
