Blem – G9 9mm Side Charging Upper Receiver (BCD Issues)

Description

* These uppers had some issues with the bolt carrier door pocket being slightly out of spec. The bolt carrier doors had to be modified slightly to function properly. These uppers function fine.  The bolt carrier doors have exposed aluminum and need to be cerakoted now. Some uppers may need also have some blemish lines.*
