Faxon Firearms Plan B to HUB Adapter - Black Stainless Steel 1.375-24

The Faxon Firearms Plan B to HUB Adapter bridges the gap between Plan B muzzle devices and the industry-standard 1.375-24 HUB suppressor mount pattern. Machined from 17-4 PH stainless steel in the H1025 condition and finished in black nitride, this adapter delivers the strength and corrosion resistance needed for repeatable, shim-free suppressor attachment.

The Plan B side accepts 29/32-24 UNEF-2B threads, mating directly with any Faxon MuzzLok Plan B-compatible muzzle brake or flash hider, while the HUB side provides a precision 1.375-24 UNS-2A thread pattern compatible with the vast majority of modern centerfire rifle suppressors on the market. One rifle setup can now host multiple suppressor systems without re-threading or crush-washer shimming.

Weighing roughly 1.9 ounces, the adapter adds minimal mass to the muzzle and preserves rifle balance and handling. Its compact form factor gives you a rugged, repeatable lockup between your Plan B muzzle device and your favorite HUB-mount suppressor, making suppressor swaps quick and dependable on the range or in the field.
