[QUOTE="budlight, post: 992360, member: 2939"] Nice......... free floating is over rated in heavy barreled 15's Because anything semi auto does not have the true bolt face ,,,,, like a target bolt gun. 223 being a light pill does not incur barrel whip like a 300 magnum. accuracy is more of a matter of bullet weight/twist/powder and velocity I am very pro at least 20 inch 223. My chrono testing has show @ 200 fps compared to 16 inch. You can download a 20 inch for better grouping. I have a 1:7 and a 1:9 20 inch 223. 55 grains are cheaper to shoot. I would work towards the best results with them. My 1:7 only likes 75 grain match bullets and would probably like even more grain pills My 1:7 actually key holes 55gr pills through paper at 100 meters. at 3300 chrono. down loaded to sub 3100 the pill makes a hole. I have to get down to 3000 to actually group. where the 1:9 groups with 3100 [/QUOTE]
