Mine's a Vanguard .257. I put it in a Bell & Carlson Medalist that had two TEETS in the forward barrel channel, I thought about removeing them but figured I could always do that later if needed. I also put a Timney on it along with a "cheapo" Nikon buckmasters. The rifle shoots well under moa with the factory TSX's. It's the first time I've shot factory rounds out of any of my rifles in a loooong time. I was & am impressed.
