I haven't been able to find a definitive answer to this question. Is the Accustock bottom metal inletting different from the inletting that my stock has? I bought a 10 fcp short action HS Precision stock for a 6.5 SAUM build and am interested in the Accurate Mag bottom metal so I can use their WSM mags. I was hoping it would be a drop in fit but Accurate Mag's website claims it will only fit Accustock models.
