Hey guys this is my first post. I am building my first AR10. I decided to use a ploymer lower. Specifically the WarrDogg from Ploymer 80. All was going well until I tried to instal the front pivot pin. The spring was protruding past the front of the receiver by about an eighth of an inch. I tried to drill the hole a bit deeper to accommodate the standard AR15 spring. The drill bit came out the side of the receiver. Does anyone know how to repair this screw up?
thanks in advance.
