This lower has subtle changes compared to a mil-spec forged, it is slightly thicker and slightly heavier, but does not have the wild lines and angles of some other brands that tend to look cool, but get in the way of handling. The magwell is slightly enlarged to speed mag changes. It will take a standard LPK, all pins fit properly, I used mostly improved parts as this build is primarily for 3 gun, an AR gold and Giessele trigger fit perfectly, as does a BAD selector. The only slight fitting I had to do was slightly shave the beavertail portion on a Magpul MIAD grip where it meets the thicker grip pocket area of the receiver between the grip and buffer tube. All in all this is an excellent lower with a practical design that included subtle custom features along with excellent fit and finish for any build. I have built on several other billet and forged lowers, and this is probably my favorite, especially combined with the MML and billet uppers. (Posted on 6/29/2016)
