Replacement threaded barrel shroud for the 16-inch civilian PS90, exposes a 1/2x28 muzzle for suppressor mounting without SBR conversion.
The Dorin PS90 threaded barrel shroud is the no-paperwork path to suppressing a civilian 16-inch PS90. The factory shroud is unthreaded; this replacement shroud exposes a 1/2x28 muzzle thread that accepts any 5.7x28-rated direct-thread suppressor without filing an ATF Form 1 SBR.
Installation is a drop-in swap of the factory shroud assembly; the barrel itself remains the factory 16-inch unit. Once installed, the PS90 stays a Title I rifle and accepts cans like the Dead Air Mask HD or HUXWRX Flow 22 Ti directly. For shooters who want suppressor compatibility without an additional NFA item, this is the right answer.
This part is currently out of stock at FN Specialties as of mid-2026. Check stock before recommending. The CMMG thread adapter is a related but different solution for SBR PS90 builds with the CMMG M12x1.0 LH barrel.
