The Oly lowers are not to the same specs as others, they did something like what Colt did. And DMPS are cast. I was thinking of PWA, BM or the such.

I've built two ARs on Oly lowers and two on EA (Armalite) lowers and can't see any difference. The first Oly is a preban SGW and I shoot the hell out of it as a 20" HBAR,then a SP1 with a rimfire and a 9mm Oly upper. It's your $, but as long as all the parts fit and function like they should your rifle won't shoot any better or last any longer if the lower is cast/forged, Oly, Colt, DPMS, ect.
