I am looking at an MGM heavy contour rifle barrel in the triangle (?) configuration. The current owner got it on trade & states a regular TC Encore forend does not fit. Does anyone know if you need a special forend to accomadate this configuration? I have contacted MGM phone & e-mail and have yet to get a reply. I like this barrel BUT if I then have to invest in a custom forend it may change my mind! Thanks for ANY input.
