The Law Tactical HK417/MR762 Gen 3HK Folding Stock Adapter is engineered specifically for Heckler & Koch rifles that use the proprietary receiver extension, giving owners a compact folding capability without compromising reliability. Machined from robust 17-4 steel with a durable black DLC finish, this adapter integrates cleanly at the rear of the receiver and uses a low-profile hinge and single-button release for smooth, repeatable operation.

Designed for HK417, MR762, MR308, G28 and similar platforms, the adapter adds a modest amount of length to the pull while maintaining full function when unfolded. It is well suited for shooters who need easier transport and storage of their rifle, whether heading to the range, training, or moving between locations. Precision machining, adjustable hinge tension, and thoughtful details like a quick detach sling point reflect Law Tactical’s reputation for careful engineering and dependable firearm accessories.
