Item Relisted! FS Proof Research 18 barrel 223 Wylde with Adjustable Gas block, gas tube, compensator...

[41MagFan]

Proof Research Carbon Barrel
Comes with proprietary PR adjustable gas block. Includes gas tube. This is NOT readily interchangeable with standard AR gas blocks AFAIK.
Gas Block is approx 1.75”

Decided to go with a different caliber in my build (6 ARC)
