Multiple inserts are available to make your Wolverine one of the most versatile silencers you own. The smaller threads will use the M14 Collar, M24 thread will use the M24 collar, and the M26 thread will use the M26 collar.

Note: Bulgarian Krinkov/SBRs take the 24mm LONG Insert

*Special note
Polish WZ88 “Tantal” rifles have a unique barrel/thread profile that we do not accommodate currently. The muzzle extends well past the threads and that does not work with our system. They cannot be cut to thread length without being an SBR. It’s an issue we may address at some point, but for now, the Wolverine cannot mount to them.

14-1mm LH

This is the most common thread pitch for eastern European pattern AK’s and the majority of US made / parts kit barrels. Common examples:
WASR-10
Century RAS-47
Century C39
Yugoslavian AK’s (Opap / Npap)
Polish kit builds
East German kit builds
Romanian kit builds
Russian kit builds (7.62×39)
Bulgarian (milled)

Common thread pitch for AK-74 rifles. These threads are on the gas/front sight block, not on the barrel. Examples:
Russian or Bulgarian AK-74’s
Russian or Bulgarian “Krinkov” AKS-74U
All Arsenal / Kvar AK’s (7.62×39 or 5.45×39)

This is primarily a Yugo thread pitch used on their AK pistols Pap92/M85. The threads are on the gas/front sight block, not on the barrel.
