The Law Tactical Folding Stock Adapter was designed for low profile transport of AR rifles in non-permissive environments. The adapter is ideal for any situation that requires a smaller profile weapon for transport and storage.

Simple one-button release folds the stock. To engage, just unfold and fire. The stock automatically locks into place once unfolded. The adapter does not affect gun function when unfolded in the standard fire position; the rear portion of the adapter is built to the same specifications as a standard receiver to ensure maximum compatibility. An integrated QD attachment point is included.

It works with direct impingement or gas piston systems and fits A2, carbine, mil-spec, or commercial buffer tube and stocks. It can be used with standard bolt carrier groups including: full auto, semi auto, 5.56 to .308.
