I originally bought this barrel with a 5.45 Tula '86 kit from Rguns, however, as we know I was told it was out of spec and Troy from InRange told me he would not install it, so I bought a BlueJack v. 3 immediately after, and all has been good since
Now what the hell do I do with this barrel? I never returned it (stupid), so what should I do with it?
