extended length inner barrel for TM SG552
I am just wondering what kind of options I have for longer inner barrel(tight bore or regular) for the SG552. I am getting an longer SPR-style flash hider and OPS silencer for the gun anyway so I figure an inner barrel upgrade would be a suitable thing to do. What else I might need to change(or better change at the same time) if I were to go with a tightbore?
Knowing that I am completely new at this, would this be a recommanded DIY job?
Thanks.
