Does anyone know where I might be able to purchase a "K" karbine version of the HW95 barrel anywhere? I see Pyramiydair has two types... One with muzzlebrake and one without, but they are standard length barrels. I cannot seem to find the shorter version without muzzlebrake and also threaded for a moderator. I may have to order one, have it cut down, and threaded, but was hoping to find the actual K version if possible. Any ideas?
