Old Tikka, one of the M658, M690, or M695 actions. The Tikka M658/690/695 Magazine S5840375 is the genuine replacement, built for exactly that family and nothing else. Capacity shifts depending on caliber, and that's just physics, not a flaw. Load it in .25-06 Remington, 6.5x55 Swedish Mauser, .270 Winchester, or .30-06 Springfield, and you get 5 rounds. Step up to 7mm Remington Magnum, .300 Winchester Magnum, or .338 Winchester Magnum, and it drops to 4. Longer cartridges take up more room. Same magazine, different math depending on what you're feeding it. Blued steel body, stainless leaf spring, polymer baseplate. This thing is built to actually work in the field, get tossed in a pack, dropped, reloaded a hundred times over a season. The matte black finish means it's not turning into a rust problem after a few wet hunts. Worth knowing upfront: this fits M658, M690, M695. Nothing else. It won't work on a T3 or T3x, and given how much Tikka's naming overlaps across generations, that's an easy mix-up to make. If you're running one of those three older models, though, this Tikka 690 Magazine or 695 Magazine is exactly the factory-correct Tikka Magazine your rifle needs.
