X-Fire/PDI is being very prolific in releasing new products early in the year, the latest one this muzzle for the AK series.... "Made of S45C, all CNC machined and black oxide finish. This is available for AK74MN completely and we're the First Japanese Maker what make it. The screw is 24mm, so you need Adapter when you attach this muzzle with AK47. Now we're making AK100 Front Sight for AK74MN. You can make AK105 with all of items!(Muzzle & Front Sight)."
