Not sure where to post this,

Does anyone have the contact information for these guys? By contact information, I mean a phone number.

I am building an AR-15 and purchased a Dezign Arms barrel through Tactical4less. Got the barrel in and it looks great. It was just cut too short. The guy at Tactical4less is difficult to get a hold of, so I would like to just go to Dezign Arms and see if the measurements given to them were correct. Kind of trying to end the telephone game when passing on information about the barrel I need for my build.

Any and all help would be greatly appreciated.
