Be careful to order the right type of hop up unit/rubber. Otherwise have a dremel kit ready. Supposedly certain hop up units don't fit into certain guns (I'm talking about one vs two piece designs). Also get the right hop up unit for the right version mechbox you have (M4/16 use V2 while AK uses V3).
The hop up rubber is like $5 while the hop up unit itself is around $15-20.
As for barrels I believe they go for something around $40-60 CAD. You'd obviously be getting a TB barrel though (like a 6.04 or 6.03mm).
As far as BB's go you cant' really go wrong with Bastards, Mad Bull, or Metal Tech.
