Zev Technologies FDP Threaded Barrel - 1/2x28

Upgrade your platform for suppressed shooting with the ZEV Technologies FDP Threaded Barrel. Designed as a direct drop-in replacement for FDP carbines and pistols originally equipped with non-threaded factory barrels, this match-grade barrel allows shooters to easily mount sound suppressors, compensators, and other muzzle devices. Engineered with ZEV’s signature precision manufacturing, it enhances operational capability while maintaining exceptional accuracy and cycling reliability.

Precision-machined from 416R stainless steel, the ZEV FDP barrel features a smooth 32 RA micro-surface finish and a durable Black Nitride coating for superior resistance against friction, heat, and corrosion. Threaded in standard 1/2x28 pitch with a 1:10" right-hand twist rate, it optimizes 9mm bullet stabilization for both supersonic duty rounds and heavy subsonic suppressor loads. Every barrel comes complete with a matching knurled thread protector to safeguard the thread crown when shooting unsuppressed.
