I recently built an AR on a Del-Ton A2 kit with an RRA lower.  Do Del Ton chromed barrels also have chromed chambers?  I don't think mine does.  Also, when shooting it, the brass is ejected with a lump pushed into it, as if there's a bump in the chamber right around the neck.  That can't be normal.  Anything I can do about it?  It fires and ejects fine, but there might be trouble if I decide to reload for it.  Thanks.

Your chamber is chromed.

The bump on the case is from the brass deflector and it is normal.  You can mess around with buffer weights to try to change it.
