Factory German made Heckler & Koch HK91 G3 Magazine Clamp. These are by far the rarest magazine clamps H&K made (they are no longer made). These only come up for sale once in a blue moon. Clamps have "H&K" markings on the front. These are used and make some scratches, dings, and light wear but function perfectly! Don't miss the chance to grab one! Sold as is, no returns/exchanges. All sales final! Picture is representative of one you will receive.
