The MDT 2-Way Lock Carbine to Fixed Folding Adapter is a practical solution for shooters running bolt-action rifle chassis with AR-style interfaces who want to reduce overall length for transport, storage, or confined shooting positions. Unlike a standard fixed stock, this folding adapter lets you collapse your buttstock when it's not in use—then locks it securely in both the extended and folded positions, so there's no rattle or shift at the range or in the truck bed.
Built around MDT's reputation for precision engineering, the 2-Way Lock mechanism uses all-steel construction to eliminate flex and movement where it matters most. When you're at the shooting line, the adapter holds your existing buttstock in rigid, straight-line alignment for a stable platform. When you fold it, the secondary lock keeps it compact and snug—no fumbling with adjustments between shooting and stowing. The solid interface does not allow a bolt to pass through, so verify your rifle's configuration before purchasing.
This adapter works with most bolt-action rifle chassis that accept AR-style fixed or carbine stocks, and it's compatible with your existing buttstock, so you don't need to buy new furniture. The exception: MDT's TAC21 and ESS chassis are not compatible with this adapter. If you're building or upgrading a precision rifle or competition rig where compactness and repeatability matter, the 2-Way Lock delivers a no-nonsense, mil-spec feel at a fraction of full-custom pricing.
