Don't worry about using duster or propane just get some propane. A lot of people don't even upgrade their slides and run propane fine (however this creates more wear and you'll eventually have to replace the slide). Slides are not a restricted part, it's actually the frame that's restricted on pistols so yeah.
okay so can use propane on a HFC 134 gun? again with a drop of lube?
I havent seen slides for same on Capital Airsoft... where can I buy them? and you are sure they would pass customs without problems?
