Description
The Dead Air Wolverine PBS-1 was built to live on AK pattern rifles, and part of what makes it so versatile is its swappable thread insert system. Here's the catch: the collar that comes in the box with the Wolverine only fits the smaller inserts, things like M14x1 LH, 1/2×28, and 5/8×24. Step up to the big M26 insert for a 26mm threaded host and you need this collar, the WV121, to lock it all together. No collar, no mounting, it's that simple.
Why the Wolverine M26 Collar Matters
Dead Air sizes each locking collar to match the insert it retains. The standard collar covers M13 through M16 metric threads plus the common imperial sizes, the M24 collar handles 24mm inserts, and this M26 collar is dedicated to the 26mm insert family. If you're setting up a Zastava M92 or similar PAP pattern pistol with those chunky 26mm left-hand muzzle threads, this is the piece that pairs with the matching M26 thread insert to get your Wolverine hung on the barrel correctly and securely.
Built Like the Rest of the Wolverine System
Like everything in the Wolverine lineup, this collar is a no-nonsense chunk of properly machined steel with a black finish that blends right in with the suppressor body. It's small and light, so tossing one in your range bag alongside a spare insert is easy if you swap the can between hosts. Once installed, it holds the insert firm so your alignment stays true shot after shot.
If you already own the Wolverine and picked up an M26 insert separately, grab this collar and you're set. Some insert packages bundle the collar in, so double check what you have before ordering. For anyone building out a dedicated large-thread AK setup, this is one of those small parts that makes the whole system click.

Frequently Asked Questions
Does the Dead Air Wolverine come with the M26 collar already?
No. The Wolverine PBS-1 ships with the standard collar, which fits the smaller inserts like M13, M14, M15, M16, 1/2×28, and 5/8×24. If you're running the M26 thread insert, you need this WV121 collar to retain it. The M24 insert likewise needs its own dedicated collar.
What firearms would I use the M26 insert and collar for?
The M26 setup is aimed at hosts with 26mm left-hand muzzle threads, most commonly the Zastava M92 and PAP pattern AK pistols. Pair this collar with Dead Air's 26mm LH thread insert and your Wolverine mounts right up to those barrels.
Will the WV121 collar work with smaller Wolverine thread inserts?
No, each collar is sized for a specific insert family. The M26 collar only works with M26 inserts, while the standard collar covers M13 through M16 and the common imperial threads, and the M24 collar handles 24mm inserts. Match the collar to the insert you're running.
Do I need to buy the thread insert separately from this collar?
This listing is for the collar only. Some Dead Air 26mm insert packages include the M26 collar bundled together, so check what you already own. If you bought a standalone M26 insert, this collar completes the mounting setup.
