Based on the comments of several very trusted individuals, including a couple of well-respected guys from the 'fire, Wyatt's doesn't seem to have the same quality and fitment as the AICS BM's, such as the Atlas...*hint*
I agree with that assessment... the Wyatts feels like a lighter metal is used over the factory mag box. I did have to tweak it a bit to keep the rounds in the box IIRC, but regardless, it wasn't a big deal.
Weight and cost over the other BM's was the deciding factory for me on that build.
