I recently removed the trigger guard on my Texan in order to remove the carrier tube so I could install the African Air ordnance Carrier tube that came with my kit. The new carrier tube is binding up on something. I've been in contact with Jeremy with AAO and he is walking me through some steps to figure it out. I reinstalled the factory carrier tube and reassembled everything. Everything went back together smoothly but the gun will not cock every time I try to cock it. I have to recock and kind of slam the cocking lever forward to get it to engage quite often. Does anyone happen to know what may be causing this?
