Stock G&P AEG FPS (Canadian version)
 

I'm trying to figure out how fast an otherwise-stock "huang x Canada Edition" G&P AEGs are supposed to shoot at.

I replaced the poor-sealing stock piston o-ring and left everything else. Chrony's slightly under the box-stated 430fps.

Ignoring G&P's totally rad track record with internal parts quality and QC consistency, what are others' results?

I was shooting about 420 with the spring it came with. About 400 with a M100, and 330 with a M90.

There doesn't seem to be a consistent FPS out of these guns.

The Magpul MOE one clocked in at 480, while the standard M4 colt body AEG came in at 395.

G&P internals :x
