I've never owned or been around ARs much. Have an interest in getting one just in case they get the ban hammer again. What would you recommend in the 8 hundred range budget or below for a .223. Buds gun shop highly recommended a smith for best bang on the dollar but it was a touch over a grand. I've found a few used Colts in the 8-9 range. Chrome lined barrel a must? Thanks in advance for advice.
