I am such an idiot. I got a stripped barrel in anticipation of using an free floating handguard, changed my mind and got a VLTOR CASV-EL system and forgot that I need to have the barrel nut and handguard cap.

There has gotta be someone in the Philly area with a set taken off from your stock barrel to put on an FF handguard and no longer need 'em. I'm anxious to do my build so I'll give you $10 for the set and will pick 'em up at your place. Thanks.
