Re: Bushmaster- Your Thoughts
I would look elsewhere as there are excellent rifles in same price range from BCM, DD, LMT, Colt.
As mentioned before, Bushy is know for problems with BCG (gas keys, bolts) out of spec chambers (their 5.56 chambers are almost always out of spec) and bad service.
Too many other great options out there to mess with bushmaster. If you own one and its working or you made some small upgrades/fixes, stick with it as will probably keep on working.
