I ordered one last night. I also ordered one of their FAL US HTS sets. I used one on my last FAL build and I like it a lot.
Funny thing, They are no longer listed on their website, but I had saved a direct link.

I wasn't sure if it would load into "my cart" but it did. It shows up on my receipt, dunno if I"ll actually get one or not.
