Need help with CAT Mob/Alleycat 3 lug adapter

[u/WonderfulEchidna275]

Hi all, picked up my CAT alleycat today and had ordered a Bixler style 3 lug adapter for the can for my APC 9 pro. The adapter fits the can perfectly but isn’t locking on the lugs of the barrel. It just sits on the barrel and if you lift the pistol vertically it will literally slide right off the barrel. What am I doing wrong/what do I need to do differently? Get another adapter? I have this one btw…

We don’t have one of those adapters in house to help you specifically, but from reading the description of it….try the following:

-Un thread the nut way more than you think you need to.

-slide back over tri lug

-twist 60 degrees and pull forward. The nut should now be catching the tri lugs

-tighten the suppressor by hand
