I have owned a Smith, Colt, RRA and a Bushmaster. Not alot of differances in all of these. You will pay more for a Colt for the name, that is on anything that says Colt. The trigger on the bushy was worse than the rest but IMO they are all gov. spec. Just get a trigger job on whatever you get if you dont like the trigger. There might be a little differance in the barrels but if your buying a tactical rifle and not a varmint rifle it doesnt matter, just get one.
