So I’m a bit dumb, when I got my tikka and stock it came with a CTR mag. But the chassis I ordered accepts AICS mags only. The chassis right handed but I milled out the left side cause I shoot lefty. I’ve read that the tikka can take both but I don’t know what mags work. I’ve tried 2 so far and the didn’t work/feed. If I could get help that’d be great
