Product Info for Gear Head Works HK MP5K Folding Arm Adapter for Tailhook Mod 1

Want the look of the original MP5k-PDW but without the stamp? Now you can have not only the look, but the same quality and operation in a pistol brace as the real stock. We teamed up with the original OEM supplier of these to HK and designed an arm to accept the Tailhook Mod 1 brace. It is made form the same materials and uses the same folding mechanism as the OEM stock. Your SP89 and clones can now have the same superior stability the Tailhook provides as the rest of your pistols. No need to put something that looks atrocious, is flimsy or is pieced together with parts from 4 different manufacturers to brace your favorite roller lock.image
