The MDT Tikka T3X SA Bottom Metal Pillar Kit is a precision‑machined set of internal support spacers designed to work with aftermarket bottom metal assemblies on a Tikka T3X Short Action rifle. When upgrading to a detachable bottom metal system—such as one that accepts AICS‑pattern magazines—this pillar kit fills the gap between the barreled action and the bottom metal to create a solid, consistent interface that ensures proper torque and alignment during installation. By providing stable, repeatable contact points, the pillars help maintain reliable feeding, consistent bolt operation, and improved accuracy potential under recoil and repeated use. This accessory is especially valuable when installing bottom metals in stocks or chassis that do not include an internal micro‑chassis, as it prevents unwanted movement and enhances the overall stability of the magazine interface. Durable and easy to install with the bottom metal’s hardware, the MDT Bottom Metal Pillar Kit is an essential component when converting a Tikka T3X SA to a modern detachable magazine platform.
