The Tikka T3 Extended Magazine S5850375 gets you 5 rounds instead of whatever came standard, with 4+1 in the bigger magnum chamberings where the cartridge itself is just too long to squeeze in a full 5. Not a huge jump on paper, but anyone who's run dry mid-hunt knows exactly why it matters. This is a genuine factory part, not some aftermarket guess at fit. Built from durable polymer, this Tikka T3 Extended Magazine is designed either as a straight OEM replacement or a real capacity bump over the flush-fit mag, and it covers a wide spread of long-action calibers: .25-06 Remington, 6.5x55 Swedish Mauser, .270 Winchester, .30-06 Springfield, 7mm Remington Magnum, .300 Winchester Magnum, .338 Winchester Magnum, and 7mm PRC. Here's the thing about having a spare loaded and ready, it changes the pace of everything. Slip it in, you're chambering the next round immediately. No fumbling loose rounds, no trying to top off a mag that's still sitting in the rifle while a buck's about to walk. Whether you're in the field or working through a range session, that few seconds saved is the whole point. If you want something that feeds exactly like the magazine your rifle shipped with, because it basically is, these Tikka magazines in this line are as close to a sure thing as you'll get. Drop it in, load it, done. It's a genuine Tikka extended magazine, built to the same spec as the factory original.
