I have a brand new never used Tikka T3x lite black stock, bottom metal and LA Magnum magazine. Action screws are not included, but the steel recoil lug is. WTS for $100 plus shipping.
A 30-06 round fits in the magazine well. On the follower, there is a capital L. I don’t know if Tikka uses the same magazine for all Long Action cartridges. But it does appear so to me.
