is a handy tool for choosing the right length of barrel
sorry OP for takin your thread off topic lol.
and agreed about external quality but jgs and echo1 guns are more for those who want an inexpensive fieldable gun that can take bit of a beating isnt too heavy to lug arond all day and u wont cry about when it breaks, once the reciver cracks or somethin then u have some experiance and can decide if u wanna lug around a metal body or not. I personnaly dont mind the plastic body guns as they arent so heavy and still work fine, but if u want the best looking most true to life (being an aeg of course isnt that true to life but u get my point) then yes a full metal gun is a good choice vfc 416 is one of my faves just havent gotten one yet.
but they are probably the nicest aeg416 i have seen
