KAK PLAN B KRINK MD M26X1.5LH

The KAK PLAN B KRINK MD M26X1.5LH is a compact muzzle device designed for shooters running suppressors on short-barreled rifles and pistol-caliber platforms. Built around KAK Industry's proven Plan B design, this muzzle brake features a tapered profile followed by M26x1.5 left-hand threads that lock up repeatably with Plan B suppressor hubs. The tapered-to-threaded design creates a proper seal, which matters if you're stacking a suppressor on an AK platform or other non-standard host — it reduces the chance of first-round pop and keeps your overall system running cleaner.

At 2.55 inches overall length with 1.55 inches of protrusion into the suppressor's blast chamber, the Plan B KRINK strikes a practical balance for compact setups where every millimeter counts. The 17-4 stainless construction handles full-auto fire and harsh suppressedrifle duties without choking. Its 5.56 and 7.62x39 bore makes it ideal for AR-pistols, short-stroke AKs, and other intermediate-caliber builds where you want serious sound reduction without an unwieldy footprint. At 3.7 ounces, it won't throw off your balance on a lightweight upper or short-barrel build.

Installation is straightforward: use Rocksett threadlocker, apply 20–25 ft-lbs of torque, and call it done. KAK includes a multi-wrench for installation. One critical note: suppressor manufacturers often reserve the right to deny warranty claims if you use a non-OEM muzzle device with their cans. If your suppressor is from another brand, confirm compatibility before threading on a Plan B — it's the smart play to keep everyone happy and your warranty intact.

Frequently Asked Questions

Will this muzzle device work with my suppressor?

Is this left-hand threaded?

Yes — the Plan B KRINK MD features M26x1.5 left-hand threads, which is standard on many AK-pattern rifles and other non-AR platforms. Double-check your barrel's thread pattern before ordering to ensure compatibility.

What do I need to install this?

KAK includes a multi-wrench with the device. You'll also need Rocksett threadlocker compound and a torque wrench capable of applying 20–25 ft-lbs. Installation itself is straightforward: apply Rocksett, thread on, torque to spec, and let it cure.
