Does not work with ap5 tri lug - Kaw Valley Precision MACH 3-Lug Mount

I got this for a silencerco omega 9 can. I have another on an octane 45 and it slips on to my AP5 no problem. I have multiple tri lug setups.. kind of the whole point of the platform.. modularity. Ease. Well I had to twist my can off this hub cuz it got stuck and had to tap the thing off with a hammer hitting a piece of wood to not mar the finish. Incredibly frustrating to say the least. Not I can’t use it on this gun. Metal material was removed from my lugs.. I wish I could include pictures. Incredibly frustrating.
