I have several questions which you guys might answer in one paragraph. Here goes. A year ago I bought an AR-15 .223 M-4. I know what accuracy is as I have a savage lrpv in a fluted .204 1/2 moa in it . For coyote on the run shootin, I enjoy the AR, but, for p.d.s which is the main fun, the carbine 14 just don't get it for that job. Will I be happy changin out the 14 for a fluted 24 (+-) on the AR-15 frame , or should I just cut my loses and sell the AR and get a bolt ? If I sell the upper and get a bull, is ther enough left of the upper to keep, or just sell upper "complete ?" I'm sure I didn't think of all the questions I should answer, but tell me what ya think. Eastern co. needs more accuracy. Thanks for your help. j.c.
