"Tall Shoulder" Parts: Most Mete and Rival frames made in 2021-2023 came with extra-wide magazine wells. The below-listed parts have extra-tall shoulders to match. Canik changed the magwell shape in 2023/2024 (fixing this problem), so these tall-shoulder basepads often won't fit the newest guns.
How do I know what I need? The first few digits of the serial number include the year of manufacture, i.e. 23xx. . . indicates a 2023-built gun. If you have 24-built gun (include all the TTI frames) DO NOT use these basepads -- you need the standard size.
The O-Ring Workaround: If you find you have a "fat" magwell and don't want to use the tall-shoulder style, you can make any of our other Canik basepads work normally by putting a 1 inch by 1/8 inch O-ring on the mag tube. The O-ring acts as a bumper, keeping the magazine from overpenetrating.
