Just a discontinued product line, I think it took so long to get it FRT approved that there was only time for a couple of shipments to make it in country. Same with the Walther G36 22lr which was actually out of production by the time it was approved 3 years later, and IRG could import only like 3 batches of whatever rifles were in the warehouses.
Not AR-15 22lr rifles have an uphill battle to compete with the AR-15 and the Ruger 10/22 in entering the 22lr market. The AR-15 types usually scratch most people's tactical itch and the 10/22 is just cheaper.
