Interesting. Shoots the same as the stock M4 WETTI with the slim nozzle, I wonder if it has a longer inner barrel (the M4 one is 360mm...of 363mmm can't remember off hand).
I had asked about the which nozzle it came with because I've seen the "SCAR" one show up recently labeled as the "CO2 Upgrade Nozzle" and packaged for the M4 (which has the long black tube and stabilizer chuck of plastic). The same nozzle is packaged for the SCAR as well...with a shorter rod.
Looks like maybe they're standardizing on this type of nozzle as the standard...which is good since that's the type that RA Tech has decided to make an adjustable FPS version for.
Thanks a bunch for the pic!
