MDT 1-Way Lock Carbine to Carbine Folding Stock Adapter

Description

The MDT 1-Way Lock Carbine to Carbine Folding Adapter solves a problem every chassis owner runs into eventually: a rigid rifle that's a pain to store, pack, or haul into the field. This adapter mounts between your chassis and buttstock at the AR-style interface, letting the stock swing to the side so the whole rig gets a lot more compact. When you need to shoot, it locks back into place with no slop or wiggle.

The heart of this piece is the all-steel locking mechanism. The 1-way lock holds everything in straight-line alignment when the stock is deployed, so you get the folding convenience without trading away the rigidity that makes a chassis gun shoot well. It adds 1.75 inches to your length of pull, which is worth keeping in mind if you're already dialed in on a longer setup.

Where the Carbine to Carbine Adapter Fits

MDT uses the terms Fixed and Carbine to describe the shape of the stock interface. The Carbine interface is the round, circular connection, while Fixed interfaces are the teardrop shape. This is the Carbine to Carbine version, so it's built for a chassis with a carbine interface paired with a carbine-style buttstock. It works with most bolt-action chassis rifles that use an AR-style interface.

Checking Fit Before You Order the MDT Folding Adapter

One thing to know going in: this adapter has a solid interface and will not let a bolt pass through it, so it's made for bolt-action chassis setups rather than semi-auto AR builds. It's also not compatible with MDT's TAC21, ESS, or ACC chassis, though the ESS and ACC have their own dedicated folding buttstock options. Give your chassis and stock combo a quick look before ordering so you land on the right interface configuration the first time.

For anyone who travels with their rifle, stores it in a shorter case, or just wants a more packable precision setup, this is one of the cleaner ways to add a fold without rebuilding the back half of your gun.
