I have an Osprey kit I'm going to be using.
I ordered the Primary Arms Seekins Precision 15" tube.
I have read that the Osprey op rod needs to be changed out for a modified part in order to interface with a free float barrel nut.
I have also read that the new Seekins barrel nuts work just fine.
I got the tube in today and am trying to figure out if this barrel nut will work with my op rod, or if I need to trade it out with Osprey.
