I've had both. I am more or less a larue fanboy.....and I shoot the stealth right now.

BUT - if you are buying the stealth brand new it ain't worth it over the BCM. If you get a good deal it's at least a little better IMHO.

The stealth's receiver is better, and the barrels are pretty much the same. The stealth rail is heavier, but maybe you aren't worried about that.
