I have dealt with Bushmaster and have found their Customer Service to be superb. Their products are some of if not the best out there. I have not however purchased or fired one of their AR's. I owned one of their M-17S Bullpups in .223. An excellent firearm and a blast to shoot.
The only reason I got rid of that rifle was to enable me to pick up my CETME in 7.62 NATO. Bigger round, greater power and longer effective range. If you want a .223 though I would highly recommend Bushmaster.
