Lambda "SMART .03" Precision Carbon Steel 6.03mm Tight Bore Inner Barrel w/ RHOP Installed for Tokyo Marui Spec AEGs
(Length: 595mm)

"Being my first airsoft gun, and the multitude of variables, even for a professional gun tech it would be difficult to diagnose a culprit without some testing. That said, the r-hop patch in the barrel I received is not symmetrical; one side is smooth and the other is crooked. I'm not sure if this is part of my problem with precision targeting or if it's a moot point since the edges shouldn't be the part contacting the BB. All I know is it looks sus and was very disappointing. I may end up having to cut out the patch and put in my own. Otherwise, the barrel itself seems really nice. No complaints there.
