OOS- doubt that deal will ever pop up again. That was half the regular price for the optic with that riser.
It won't. They were special ordered by a rifle manufacturer that cancelled the order so PA was stuck with them so they sold them at a discount. Glad I got mine when I did on Cyber Monday. Ordered one of their flashlights (really nice), a TLR-1S and some Surefire EarPro.
