besides bushmaster lowers they're just too expensive.  from what i understand anyway as long as its forged and a reputable company, the lower brand dosen't matter.  but which has the best fit and finish to a post ban BM upper?  i'm commited to getting a BM upper because i want chrome lined and i know they are one of the most reliable, but i'll take what ever lower is forged, not too expensive, and has a decent match.  

can you guys help??
thanks.

If you're that set in using a Bushmaster upper then you should just go ahead and get the matching lower.

I just built a Bushmaster a couple months ago and was immediately set on one of their uppers and after a lot of thought, debate and research I decided just to go ahead and spend the little bit of extra cash for a Bushmaster lower to match.

Obviously, the fit and finish are perfect and I do not regret spending the extra money at all. In my opinion, if you're going to do something, do it all the way and make sure you do it right.
