The KAK Plan B AK74 is a muzzle device designed for AK74-style and other 7.62×39MM rifles with M24×1.5 RH (right-hand) muzzle threads. Plan B muzzle devices use a taper-then-thread design, and because of this, you get a tight seal and a solid fit between the device and the suppressor adapter. As a result, your suppressor aligns consistently and precisely on every mount.
In addition, the KAK Plan B AK74 is fully compatible with Plan B suppressor hubs. Furthermore, it protrudes 1.55″ into the blast chamber and measures 2.55″ overall. Moreover, at 3.5 oz, it is light yet durable, since KAK builds it from 17-4 stainless steel with a nitride finish. The package also includes an installation multi-wrench. When you install it, use Rocksett and torque to 20–25 ft-lbs for a secure fit.
However, there is one important thing to keep in mind. Some suppressor manufacturers will not honor warranty claims if you use non-brand muzzle devices. Therefore, always confirm compatibility with your suppressor manufacturer before purchasing the KAK Plan B AK74.

KAK Industry machines their Plan B AK74 muzzle devices to consistent tolerances for a secure, rattle-free fit on AK-pattern barrels. The nickel finish provides corrosion resistance and a clean appearance on most AK-pattern builds. In addition, the device threads securely onto the barrel crown for a solid, stable installation. Furthermore, the AK74-style porting reduces visible muzzle flash and redirects gas away from the shooter during firing. Also, the Plan B is available in both left-hand and right-hand thread pitches to cover the full range of AK-pattern barrel configurations. When you need a reliable AK74-style muzzle device with a quality nickel finish, the KAK Plan B delivers consistent performance on AK-pattern rifles in 7.62x39MM.
