Not sure which fits?
Use the Plan B muzzle device guide to compare functions, thread pitches and suppressor mounting considerations.
Read the guide →Choose the mounting path, then verify the complete system.
A Plan B compatible muzzle device creates one firearm-side mounting path when paired with a matching suppressor-side Plan B mount. A direct-thread HUB adapter instead connects a compatible HUB suppressor directly to the confirmed muzzle thread. These are alternative paths, not components to stack together. Peel washers are separate timing hardware and do not change thread or bore compatibility.
