The KAK Plan B Krink muzzle device in M26x1.5 LH is a face-mount muzzle device from KAK Industry (brand part no. 412-2103-021), machined in house for shooters who run a suppressor on a Plan B hub mount. The threads are left-hand, so the M26x1.5 LH pitch is the first thing to match against your barrel. A taper ahead of the threads gives a repeatable lockup and a proper seal against the suppressor adapter. It is a straightforward upgrade for a rifle that will spend most of its time behind a KAK Plan B suppressor system.

Key Specifications

• The thread is M26x1.5 LH, a left-hand metric pitch, so confirm your barrel matches before ordering.
• The device is made from 17-4 stainless steel, a tough alloy that stands up to repeated suppressor use.
• The finish is nitride, a hard surface treatment that resists wear and corrosion.
• The listed bore sizes are 5.56 and 7.62×39, which tells you which projectiles the device is built to pass.
• The mounting style is face mount, with a taper followed by threads that locks up the same way every time.
• The seal is made between the device and the suppressor adapter, which is why it is built for Plan B suppressor hubs.
• KAK recommends 20-25 ft-lbs of torque at installation, which keeps the device from backing off.
• KAK recommends Rocksett for installation, a thread-locking compound suited to muzzle device threads.
• Timing shims are included, so you can set the device to the position you want on the barrel.
• An installation multi wrench is included, so the tool you need to fit the device comes in the package.

Frequently Asked Questions

What thread does this Krink use? It uses an M26x1.5 left-hand thread, so it only fits a barrel cut to that pitch. The Krink is also made in M24x1.5 RH and M22x1.5 RH versions for other barrels.

Does it work with any suppressor? KAK recommends its own Hub mount because of the unique design of this device, and says other brands may or may not be compatible. Plan B muzzle devices are compatible with Plan B suppressor hubs.

How should I install it? KAK recommends Rocksett and 20-25 ft-lbs of torque, and the timing shims and multi wrench are included. KAK also notes that some suppressor makers will not honor warranty claims if other brands of muzzle devices are used with their suppressors.
