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.
