KAK PLAN B UNIVERSAL MZL DV 11/16X24

The KAK Plan B Universal muzzle device is a precision-engineered suppressor adapter built for shooters who demand reliable, repeatable lockup between their rifle and suppressor. This 11/16x24 threaded device features KAK's signature tapered-then-threaded design, which creates a proper seal with Plan B suppressor hubs and eliminates the loose, inconsistent fitment common to undersized adapters. If you're running a suppressed rifle and want confidence that your muzzle device will stay put, the Plan B delivers straightforward engineering without gimmicks.

Machined from 17-4 stainless steel, the Plan B is built to handle centerfire recoil and suppressor weight without shifting or rattling. The universal bore design works across calibers, and the milled flats make installation straightforward—no special tools needed. Thread pitch is engraved directly on the device for quick verification before you torque it down.

Installation is simple: use Rocksett and apply 20–25 ft-lbs of torque. That's it. Keep in mind that some suppressor manufacturers will not warranty their cans if used with third-party muzzle devices, so verify compatibility with your suppressor before you commit. If you're building around a Plan B suppressor hub, this adapter is the natural choice.

Frequently Asked Questions

What suppressor hubs does this adapter work with?

The KAK Plan B Universal muzzle device is compatible with Plan B suppressor hubs. Because suppressor manufacturers have different warranty policies, confirm with your suppressor maker that third-party muzzle devices will not void coverage before installation.

What torque spec should I use?

Install the Plan B using Rocksett (a threadlocker rated for precision rifles) and apply 20–25 ft-lbs of torque. The tapered design ensures proper engagement at these standard specs.

Will this fit different calibers?

Yes. The universal bore design works across calibers, making it a flexible choice for shooters who run multiple rifles on the same suppressor system.

Does it include installation tools?

The milled flats on the device allow standard armorer's wrenches or adapter tools to grip and install it. You'll need to supply Rocksett separately; torque is 20–25 ft-lbs.
