Thread: 6x45 Rem barrel

Depends on the .243 barrels knox profile/length.
The Rem Mod 7 has a 1-1/6" tenon thread and needs to be about another 1/4" larger than that for the shoulder to pull up on the recoil lug.
Ive cut down quite a few .243win barrels for 6x45s but most for smaller tenon threads such as Sako, CZ and Zastavas
