Tikka Ace Mag Well T3X CTR Mag S540219674 is a modular upgrade designed to unlock double-stack magazine compatibility for Tikka's ACE chassis series. It fits models chambered in .223 Rem, 6.5 Creedmoor, and .308 Win, enabling a rapid transition to higher-capacity metal CTR magazines.

The Tikka Ace Mag Well - T3x CTR works by swapping directly into the ACE chassis, which uses an interchangeable magazine well system from the start. Once this well is in, the rifle accepts the same metal double-stack magazines found in the Tikka T3x CTR, T3x Tac A1, and T3x Arctic lineup, giving shooters a real capacity bump over the standard single-stack polymer mags the ACE Game platform ships with normally.

All components are built to Tikka and Beretta quality standards, and the metal construction is meant to hold up in both field and tactical environments rather than wearing out after a season of hard use. This Tikka ACE magazine well is engineered for smooth, reliable insertions and feeds, precision-fit enough that seating a magazine does not require any extra force or fiddling to lock it in place.

Installation follows the same swap-out procedure as any other ACE magwell, no specialized tooling needed. That is really the whole point of the chassis design. A shooter running the same Tikka T3x ACE rifle across a hunting season and a range day can switch between single-stack and CTR-style double-stack magazines depending on what that particular outing calls for, without needing a second rifle or a gunsmith visit.

Key Features:

• Converts ACE chassis to CTR-style double-stack magazines
• Compatible with .223 Rem, .308 Win, 6.5 Creedmoor
• Durable metal construction
• Precision fit for reliable feeding
• Simple swap-out installation, no special tools
• Factory-grade finish matching OEM components

This Tikka Ace Magwell gives ACE-chassis owners a genuine path to higher magazine capacity without giving up the modularity the platform was built around.
