US
Great milspec kit
always purchase these for any upper build; pretty par for the course
USDust cover and forward assist
The finish on the dust cover was a bit well not perfect however for the price of the dust cover and forward assist kit I can't really complain because it works like it should and that matters more to me than anything else.
