KAK PLAN B UNVRSL MZL DEVICE 5/8X24

The KAK Plan B Universal Muzzle Device in 5/8x24 is a precision-engineered adapter designed to provide a secure, repeatable connection between your rifle's barrel and a Plan B-compatible suppressor mount. Built in-house at KAK Industry, this muzzle device features a tapered design followed by threads that ensure consistent lockup and a proper seal every time you mount or remount your suppressor—critical for both accuracy and suppressor longevity.

Machined from 17-4 stainless steel with a nitride finish, the Plan B holds up to hard use in the field or at the range. The device is engraved with its thread pitch (5/8x24 in this case) so you'll never mix up your adapters, and the milled flats make installation straightforward with a wrench. At just 1.6 oz, it adds minimal weight to your setup, and at 1 inch overall length with a .895" outside diameter, it integrates cleanly with most rifle profiles.

KAK Industry's precision manufacturing ensures this adapter will work reliably with Plan B suppressor mounts. Installation is straightforward: apply Rocksett to the threads and torque to 20–25 ft-lbs. This muzzle device is a no-nonsense solution for shooters who want a repeatable, durable interface between their barrel and suppressor, without the guesswork.

Frequently Asked Questions

Will this Plan B muzzle device work with my suppressor?

The KAK Plan B is designed to work with suppressor mounts compatible with Plan B adapters. Before purchasing, confirm that your suppressor or its mount is Plan B-compatible. Some suppressor manufacturers require their own brand of muzzle device for warranty coverage, so check your suppressor's documentation.

What thread pitch do I need?

This model is 5/8x24. That's the standard for many rifle platforms, but verify your barrel's thread pitch before ordering. The muzzle device is engraved with its pitch so you won't mix it up with other adapters.

How do I install the Plan B muzzle device?

Apply Rocksett threadlocker to the threads and torque the device to 20–25 ft-lbs using the milled flats with a wrench. Do not over-torque.

How much does this add to my barrel?

The Plan B weighs 1.6 oz and extends 1 inch from the muzzle, making it a minimal addition to your rifle's weight and length while maintaining a low-profile .895" outside diameter.
