They were bought out by the freedom group, which is the company who owns Remington in November. Then came Sandyhook craziness and the freedom group considered ending all AR manufacturing. I called the LAR office a while back (january) they are still cranking out milspeck uppers and lowers, but they told me that they had no idea about if our when they will make a new batch of ops-4s.
You will no longer be able to by direct, they closed down their little showroom and they will only ship to FFL accounts.
I have been looking for an ops-4 stripped upper for 3 months. I final bought one on Gunbroker but I had to pay way more than retail. ( Almost double, but I really wanted one). Some stripped ops -4 uppers i was watching sold for $800-900, 3X normal retail.
There are a few built ops-4 rifles for around $1800 on the classifieds and gun broker.
