This thread adapter replaces the outer barrel completely on the KJW MK.2, this version does not include an integrated front sight.
Please Note: This thread adapter is desgined to shorten the outer barrel portion of the gun; as a result of this, the inner barrel sticks out of the end of the adapter approximately 50mm(2"). The adapter is designed to allow the user to attach a mock suppressor without making the pistol too long to use. If you plan on using your Mk.2 without a mock suppressor and want the barrel to sit flush with the end of the adapter then you will need to cut your inner barrel down to allow for it to sit flush with the end of the adapter. If you need assistence doing so, please contact me; I can offer a barrel shortening service to you.
