I am thinking about getting a WETTI AWSS M4 GBBR GEN III
But I can not decide between the CQB version or the regular version of the two variations avliable
combine this handgraurd

with this barral
http://torontoairsoft.com/product.php?id_product=434
to make one gun without having to by both of them
basicly I am asking what M4 R.I.S hangaurd fits the the regular version?
or what standerad sized (I think 14inch) M4 barral fits the CQB version?
