I called Osprey today they answered on a cell even though it was after 5pm. I can order the Op-Rod for the mid length gas port barrel I got for 37.50 direct no problem. Will do so after 9 am Thursday. He said they have those in stock. Said I should have in 3-4 days. Will finally have an AR until my backordered barrel arrives. Great Company to deal with he was even complaining about 5.56 ammo. When they do a design mod they have to test it for the military using M189 5.56 ammo. Lake City. He said as a company they have 5,000 rds left. Even hard for them to find ammo. And he was blown away by the lack of 22lr ammo out there. He said he himself had about 12,000 rds of 5.56 Lake City at home but may end up selling some to Osprey.
