I was looking at trying to do a simple upgrade on my Specna Arms SA-E04 EDGE River Rock Arms. Was thinking about just the barrel and hop rubber. I don't really want to attempt opening up the gearbox etc as I don't have a spare to fall back on!

I was looking at getting this 285mm inner barrel (from a quick measure flash hider and outer barrel will still keep it covered):

Edit: After a bit more research I realised a macron is probably more suitable for me then the MR hop:

Are these sensible enough upgrades, is there anything else worth doing that's easy?
