Mossberg 500 “Shockwave” PGO Build
This video details a custom Mossberg 500 Shockwave build, emphasizing its legal classification as a PGO firearm due to the absence of a shoulder stock. Key modifications include a 14-inch barrel, Raptor grip, MOE handguard, and a 3D-printed hand loop. The build's overall length exceeding 26 inches is crucial for its legal status, distinguishing it from traditional shotguns.
