I went with a Stiller for my build as I was trying to keep costs to minimum. After having it for a while, I can see some of the minor issues that I have heard are not there on top tier stuff like the defiance. I doubt there would actually be much, if any accuracy difference, but they still bug me. One is that the ejector hole has micro rough edges that prematurely leave a slight ejector mark on my brass, which can make detecting pressure difficult. The other big one is that my bolt lugs are not making 100% contact. According to Stiller, lapping the lugs voids the warranty as well...
I am completely happy with their bases, but with high recoil guns and muzzle brakes
, I would either pin or bed the base to the action.
If I had to do it again, I think I would open up the wallet and let loose of a few extra $$$ and get a Definace with the integral rail.
Just my $.02
