I am buying a new .223 AR (on the low end of costs) I am looking at basically 2 models the gun will be used for Yotes and Bobcats in VA at our farm and a Backup to my .243 for P-dogs out west once a year. I am stuck between a Sporter type barrel and a Bull Barrel. Both are the same costs I am weighing my options with the slightly elevated round count of P-Dogs. The weight difference is 2.5 Pounds. Any input would be great.
