Cansoft WE is the exact same as non-Cansoft WE, with the exception of the clear part of the reciever. From what I've seen/heard about the WE, they seem to be rather more popular than KJW, I've seen more WE than I have KJW, the WE also seems to work with most real parts as well with little to no modifications as they seem to be fairly milspec. I'd head on over to

I won't spend much on sub-par items and I'll jsut say this: I have a WE M4A1 and SCAR-L on the way, and it's not because they're crap :P
