Sending in the frame for a new barrel, it will be used for varmit hunting, in missouri, does anyone know the weight difference between these two barrel lenghts in .223, is the extra 2 inches of barrel worth the weight and lenght ive heard that the 24" has a marked amount on incresed velocity but not much edge as far as accuracy, i know these topic have been covered, but looking for new and more info, thanks.
