to make it easy, could u Albert Einstein plz simply tell me watz the longest inner barrel i can have, without any problem....plz.....simply english plz

講得簡單D就係話, 個氣筒內的空氣唔夠係BB彈離開內管前充滿氣. 拍頭會跟住向後拉, 吸番內管入面既空氣入去.
你會見到BB彈初速會低左, 同埋彈道十分之唔stable.
AEG都會有同一現像, 試下放M4 cylinder落條509管你就會明.

363mm mate

Elf

in fact you can have a 363 inner barrel and get a 20 inch outer barrel. it works

michaelredknapp

363mm only..........
so what is the size of outer barrel if the inner is 363mm??

Elf

standard M4 length 14.5"

michaelredknapp

well, i dun want my weapon LOOKs long, so if 363mm is the longest barrel the cylinder can carry,  i'll go for the shortest outer which fit the inner length....

Elf

如果一定要長管的話, 之前 "大tech"有出過一個銅座, 係可以用電鎗管, 不過條電鎗管個hopup位要執到同ptw管一樣
