🛠️ Built Like a War Tool — Because It Is One.
The #51660 is purpose-built to take abuse — whether in desert heat, arctic cold, or humid swamp conditions. It cycles everything from buckshot to breaching loads without hesitation. Even after hundreds of rounds, the action stays tight, and the feed remains consistent.
The thick-walled barrel gives it serious front-end weight, reducing muzzle rise and making it easy to stay on target during rapid strings. Combined with the ghost ring sights, it feels more like a precision tool than a shotgun.
👤 User Impressions:
“Feels like it was forged for war. It’s heavy, sure — but that weight becomes your friend the second you fire 00 buck and realize how flat it shoots.”
— RCMP operator, Alberta
“Everything about this gun says duty. The action’s confidence-inspiring, and it eats everything I load. It’s not a toy — it’s a tool.”
