Overview
The Law Tactical AR Folding Stock Adapter Gen 3 is a steel assembly designed to allow the stock of your AR-15 to fold to the side, creating a more compact profile for storage or transport. This adapter is compatible with Mil-Spec carbine buffer tubes, which means it can seamlessly integrate into most standard builds without compromising structural integrity. Builders often utilize this folding stock adapter in mid-length gas system configurations chambered in 5.56 NATO for a versatile and maneuverable firearm setup.
Law Tactical AR Folding Stock Adapter Gen 3 - HK was the third most added stock adapter on GunPartPicker in August 2026, behind the SIG Sauer Stock Adapter - 1913 Interface Folding Knuckle, with about 14% of all stock adapter parts added to builds. That's its 3rd straight month at #3. Builds with this stock adapter are mostly chambered in 5.56 NATO (68%, then .223 Wylde 17%), split between mid-length (51%) and rifle-length (25%) gas systems, and mostly AR-15 (85%, then AR-10 13%).
It was out of stock everywhere we track for all of August 2026, and today none of the 2 retailers we track has it in stock right now. Listed prices start at $369 at BattleHawk Armory for when it comes back.

LAW folder gen 3 with HK style end cap. function works as advertised, gun runs with the stock folded for transport. one nit, the QD socket on the HK end cap is at an angle that doesnt suit a single point sling from the carrier, used the lever lug for sling instead
Law Tactical AR folding stock adapter Gen 3 with HK interface has a comfortable cheek weld for shouldered shooting once unfolded. Folded compactness is what you buy this for. Lockup is positive in both folded and deployed states.
Law Tactical AR folding stock adapter Gen 3 with HK interface has no wobble in either folded or deployed states. Lockup is positive in both positions. The HK style stock connection is a unique alternative to standard AR stocks.
