Black Rain Ordnance BRO-22 A2 Thread Protector Features The Black Rain Ordnance BRO-22 A2 Thread Protector is machined in-house specifically to protect the 1/2x28 threads on a BRO-22 barrel from dirt damage and corrosion when no muzzle device is mounted. Built from nitrided steel the protector resists wear and corrosion from repeated handling and exposure to the elements giving it a service life matched to the barrel it protects. Its design takes cues from the classic A2 style muzzle profile giving the rifle a clean purposeful look at the muzzle end rather than leaving exposed threads. This straightforward design threads on and off easily when the shooter wants to swap in a compensator flash hider or other muzzle device. Finished in black to match most factory barrel finishes the thread protector blends in visually while doing the practical job of shielding the threads from damage during storage transport and field use. Because it is purpose built for the BRO-22 barrel s 1/2x28 thread pitch it installs with a precise fit rather than the looseness that can come with a generic universal thread protector. Shooters who frequently swap muzzle devices benefit from having a dedicated protector on hand to keep the barrel threads undamaged between installs. The Black Rain Ordnance BRO-22 A2 Thread Protector is a simple affordable way to keep a threaded barrel ready for its next muzzle device.
