Problems with each

The hex screw loosed really badly on the 733,
giving me barrel woble so tremendous that foregrips can’t stay
on, but it can be tightened and fixed
After 2 skirmishes, I heard rattling inside the stock of the
m16a3, opened it up, took battery out and little pieces of plastic
(2) came out everything was fine, until today, I noticed the
stock was splitting at the top
the CA 1 piece barrel is much nicer it has the proper NATO 1/7
markings, unlike the marui, which is too shiny and has none
a reciever pin fell out of the 733, forcing me to borrow from
an in-pieces CA m4

CA 2.7kg TM 1,3
