Those are all commercial grade hobby guns, to include Oly, Stag, LWRC, S&W M&P15 and everything else that's not a Colt, LMT, DD, BCM, which are military grade weapons. Same for Noveske and KAC, which are built beyond the TDP and what I classify as 'boutique' military grade guns, because of the additional quality built into them, as well as the associated costs. The M&P15 is the best of the commercial grade guns IMHO.
