KAK Industry Plan B Compatible Universal Muzzle Device - 11/16x24 Thread Pitch - Black Nitride (SKU: 414-2103-001 | UPC: 811163036139)
Product Description
Engineered for shooters demanding seamless integration between heavy-caliber platforms and quick-detach suppressor mounting systems, the KAK Industry Plan B Compatible Universal Muzzle Device delivers exceptional lockup and concentricity. Precision-machined to accommodate big-bore barrel profiles requiring an 11/16x24 thread pitch, this muzzle device expands your host rifle options without compromising structural integrity or suppressing capabilities. It provides a solid taper-mount interface designed specifically for Plan B style suppressor mounting adapters.
Manufactured from high-strength alloy steel and treated with an ultra-durable Black Nitride finish, this adapter inherently resists extreme carbon fouling, heat erosion, and harsh ambient corrosion. By leveraging a taper-mount sealing surface ahead of the mounting threads, it effectively protects thread engagement from carbon build-up, ensuring smooth, repeatable installation and removal of your sound suppressor even after heavy strings of fire.
Whether you are running big-bore lever rifles, custom large-caliber AR platforms, or specialized precision bolt guns, the KAK Industry Plan B Universal Fit Muzzle Device acts as a rock-solid bridge to modern suppressor technology. Compact, lightweight, and streamlined, it functions as a minimal-footprint muzzle device when firing unsuppressed while serving as an uncompromising mount when running suppressed.
*Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix:Staging & Installation Protocol:
- Barrel Thread Pitch: 11/16x24 tpi (Common on select big-bore barrels such as .458 SOCOM, .450 Bushmaster, .45-70, or custom heavy barrels).
- Suppressor Compatibility: Plan B Mount Pattern / Q Cherry Bomb compatible mounts and adapters.
- Max Caliber Clearance: Verified for big-bore projectiles up to .458 caliber (always verify pass-through alignment with a alignment rod prior to live fire).
- Ensure the firearm host is completely unloaded, cleared, and secured in a bench vise using proper barrel blocks.
- Thoroughly clean and degrease the barrel muzzle threads (11/16x24) and shoulder using isopropyl alcohol.
- Apply a medium-strength, heat-resistant thread-locking compound (such as Rocksett) sparingly to the male barrel threads.
- Hand-thread the KAK muzzle device onto the barrel shoulder until fully seated. (Note: Taper-mount interfaces typically do NOT use crush washers or shim sets to maintain absolute concentricity).
- Torque the muzzle device using a proper wrench to 25–30 ft-lbs. Allow thread-locker to cure fully before mounting a suppressor or live firing.
Key Features
- Universal Plan B Architecture: Seamlessly interfaces with Plan B suppressor mounting hubs and quick-detach adapters.
- Big-Bore Thread Pattern: Precision-cut 11/16x24 thread pitch engineered specifically for large-caliber or thick-wall barrel profiles.
- Precision Taper Interface: Uses an external taper angle to form a gas-tight seal forward of the threads, preventing carbon locking.
- Black Nitride Finish: Heat-treated QPQ Nitride coating offers superior surface hardness, lubricity, and corrosion resistance against harsh propellant gasses.
- Compact Profile: Minimal length and weight addition to the muzzle end to keep the host weapon balanced.
