Last week I bought 2 Anderson uppers and lower. After assembly of one of em, there appears to be a binding issue with the BCG. The lip the charging handle grabs ahold of is digging into the charging handle causing it to "wash out" the aluminum pushing the charging handle up to become wedged between the roof of the upper and the BCG, resulting in a complete lockup of the system. I have tried all different combinations of the upper/lower/bcg with a working AR and the only constant in the binding is the upper. Anyone have any ideas on the topic. Ive already email Anderson arms and am awaiting their reply as well.
