FC-330 FPS chasing pusher

Friend wanted a little more performance out of the AKBM (AKBlasterMods) FC-330. The factory pusher has a pretty narrow ID. So This was my solution - as there's not a lot of sidewall left - Designed around a piece of 10mm OD, 8mm ID stainless tube - 74.9mm long - should be a fairly snug fit, RTV/Epoxy/Superglue to secure tube to prints - Does have a stop ridge to keep the airflow less disturbed - so you'll need to cut the tube fairly accurately. May or may not work with your mags - Some feed lips seem narrower than 10mm, I'd measure first. With a cut down K25, and Worker HE (red/orange) darts - pushing 250fps now - Now needs more barrel to push farther.
