Prefit barrel ???

[deerhunter85]

I just pick up a mod.10 with a aftermarket prefit in 223 it is a 22" 11crown moly barrel varmint contour and I cannt find any name on it to see how made it I think it is a ER brown but not sure the only markings I can find is inside by the bolt face and it has 223 on it not 224 like a barrel blank but 223 any one have any ideals

I think your referring to ER Shaw. Sounds like a shaw barrel to me.
