The Tikka Ace AR Adapter S540219160 solves a problem that's specific to the ACE chassis: what if the AR-style buttstock you already own, and already like, could just bolt right on? That's exactly what this adapter does. It's a genuine factory piece that lets you replace the standard ACE stock with any AR-pattern buttstock instead.

This Tikka Ace AR Adapter is built from durable metal with a black finish, and the fit is exactly what you'd expect from an OEM part, tight, gap-free, no play between the chassis and whatever AR stock you mount. That matters more than it might seem. A loose interface here would undercut everything the ACE chassis is built to deliver in terms of consistency and repeatability.

Once it's on, you get real flexibility: length of pull, cheek position, recoil management, all the adjustability that comes standard with the AR stock world, now available on your Tikka. Whether you're chasing a specific tactical setup, dialing in a competition rig, or just want a hunting rifle that fits you better, this ACE Adapter opens that door.

Installation is a drop-in job, no drilling, nothing permanent. Compatible across both T1x and T3x Tikka ACE chassis platforms, in both Target and Game configurations, so it's not limited to one specific variant of the rifle. This is one of the more genuinely useful pieces in the lineup of Tikka accessories, precision Tikka engineering meeting the modularity AR shooters already know.
