People said it couldn’t be done. They said the AK has too many inherent issues. It has to be tuned, or specially built, or muzzle threads fixed. But the Wolverine PBS-1 addresses all but the worst builds. Just mount it, and shoot. It is the perfect balance of low muzzle noise and minimal back pressure. It boasts classic Combloc looks with state-of-the-art materials and internals. Carefully balanced sound quality, toughness, and versatility are the calling cards of the Wolverine PBS-1. Go ahead and shoot it on your favorite SBR Krinkov, or put it on your full auto RPK. It is built to handle it.
