Finally got an email response back from David Falkenhagen at Sig (I had asked when they might have LT-40 ARFs back in stock). It's bad news for getting ANY of their ARF kits at all. Here is what he said:
"We are experiencing serious problems with the supplier in China. Consequently, we do not anticipate that we will be receiving any ARF kits in the foreseeable future. Should that situation change, we will place a notice to that affect on our web site to let everyone know they are available again".
We are sorry we couldn't give you better news.
