I order with them quite frequently. Currently have a sling/bayonet/scabbard on the way from them. My first order with them was back in 2004, had an excellent deal on 8mm ammo, 1,000 rounds for $63. Wish I could find that now'a'days. I order my K31 ammo from them, found a K31 accessory pouch through them, ordered a replacement handguard for my 91/30 when they had them, and my spotting scope from them.
But again this is my experience with in stock items, I've only ordered one thing that was on backorder and that was my K-31 ammo, didn't have any problems with it though. It's also the internet, I've done it once or twice myself try to order something but it's on backorder and they haven't updated the webpage. They had a two'fer on the tactical lights, ordered it on the web page but they were sold out when I went t confirmation.
