I just received a BNIB Oly 9mm upper, 16" Heavy Bar, purchased from Gunbroker dealer. Since the unit was missing the handguard, I noticed that
there is no Gas tube. Is this normal?
There is a spring assembly, located under the bolt carrier, going from left to right hand side of the receiver, with one of the legs pushing up on the undercarriage of the bolt carrier. What's up with that?
I tried posting couple of pics, but I get this pop up window, asking me to enter the URL for the image, with no option to browse my pc to locate? Any suggestions on how to load images?
Tnx for all the suggetions
