I think I PM'd you about this, but if you go the flat hop or R-hop route then certainly go for a VSR bucking - the lips on them make a better seal with the cylinder. I'm not hugely familiar with the EdGI barrels but I assume he's been putting the VSR grove in them as well as the AEG ones?

Come to think of it, you're using an VSR barrel aren't you? Oh. :S

Yer it's a bridged window, but VSR cut for buckings
