To my perception that is abandoning the U.S. market for the TCM Rifle.
Lots of rumor as to why, my semi-educated guess is that it is related to their erratic/poor accuracy and so many being returned.
Now selling new 9mm barrels and modifying the customers bolt and feed-ramp.
Final assembly and head-space setting by a local gunsmith will be cheaper than shipping the rifle back and forth was.
Only about $7.00 to send me the bolt and feed-ramp.
Since I no longer handle the host action there is no need for an FFL or record keeping.
Now using Green Mountain barrel blanks since I exhausted the supply of IMI blanks.
"Cup" non-NFA barrel for suppressor use $400.00
You may need a local gunsmith to adjust head-space since I cannot set it perfectly without the action.
If it's too long the shoulder can be cut back on a lathe, if it's too short a light cut with a chamber reamer will correct it.
