Before getting into upgrades I want to know if this behavior of my brand new TM 5.1 is normal: When trying to see the piston head and pulling back the nozzle, it gets stuck after about a quarter of an inch. When I wiggle a little at the piston, it unsticks and I can move it back until I see the piston head. It shoots normal as far as I can tell, but in comparisson, my KWA's nozzles just move back and forth freely.
It seems to stick at a small edge where BBU and slide connect - is this bad QC by Marui? Even though a change of slide and BBU is scheduled, I still like to know if I got a lemon or if this somehow is in the range of "normal" with the TM 5.1.
Any insight greatly appreciated - thanks!
