I recently picked up my first billet lower for my SBR. A local tool shop recently started making AR's and while I was there to initially get my forged lower engraved, I wound up buying one of thier billet lowers and got a complementary engraving. The owner was really nice and gave me a tour around the shop, showed me some of the custom AR's people have ordered, and even took me out to lunch while my lower was being engraved. (It takes a really long time BTW.) It was super easy to install the LPK and every upper I had fit unlike some of the forged lowers I have owned over the years. So far I am impressed with the lower and with the company.
