Been striking out lately trying to find a fixed barrel adapter that fits the Liberty Mystic/Infinity and GemTech Multimount threading for a muzzle thread M16x1LH.

My form 1 can is being recored to be able to support .45.

I just purchased a Kriss Vector in .45 and the barrel is threaded M16x1LH.

My can is set up to accept Liberty/GemTech adapters. I currently have the GemTech LID for pistol and the Liberty UZI FBA so that I can run that can on a variety of guns.

Liberty will make the M16x1LH FBA for $150 but that seems kind of steep. I know I can go with an HK 3lug muzzle device in M16x1LH and purchase a 3 lug mount from either Liberty, SDT, or other sources but that is me in the same boat price wise.

GemTech makes a FBA for their GM45/Lunar45 that is threaded M16x1LH but I don't know that the GM45 shares common threads with the GM9.

Any leads where I can source this FBA?

Call liberty cans they’ll custom make mounts.  I have the MPX mount which is technically a custom build.
