There seems to be more than several options for metal upgrade barrels which then raises more than several questions…
on ebay they sell an 18cm metal inner barrel with a 20cm metal outer barrel. Does anyone know how this works? Wouldn’t the outer barrel be too long?
I think I want to go for a 27.5cm inner barrel and mod a hop up in the silencer like Low Guido. What would be the best inner barrel to buy and where would I get it from (links please)? Also I’ve seen a 7.1mm inner barrel too, would that work with most milkies? I want mainly accuracy would the 7.1mm inner be the best option there?
If I were to go for the longer 27.5cm inner barrel would a full cylinder be optimal for that barrel length? Would an ebay cylinder with the cooling grooves be any good? I think I read somewhere that someone was getting 280ish fps with the standard ported cylinder, 1.2 or 1.3 spring and a longer barrel. Would changing the cylinder even be necessary? Would I see gains going to a full cylinder?
Here’s a pic of my real holo sight, just an ebay el cheap’o but pretty cool none-the-less…
