Well I bought a new to me but used 243 22'' standard contour barrel. It is in great shape and I was a little worried about how it would fit my receiver. When I put it on my receiver it fit perfect. just like it had come from the factory. If it had not I probably would have traded it or resold it. The story behind this barrel is I bought it from Flitz ( He never shot it ) who bought it from Myarmor. I spoke with Myarmor and he said it easily shot under an 1'' at 100 yards. These barrels sure have a way of making their rounds ,around this site. Just thought I would fill you guys in. Range report comming soon. Dale
