Lakefield mossberg mark 3 semi auto. Does it take the same mags as the savage mark 2? Or savage 64? I remember at one time trying a savage mag in a mossberg with the black plastic fold down for end and it working but cant remember exactly which mag i used and if it was just a freak thing or if they infact are interchangable. Can anyone confirm? Im out of town and my buddy has asked me to find him a mag for this lakefield mossberg mark3
