What will you prefer, i like to be a medium or small bodytype, and for attachments i'll probably use a grip or something in that genre for more accuracy or less recoil. What will you use?

Careful, the former kind of topics are done quite often. Here's http://www.gamesas.com/index.php?/topic/1177971-what-body-type-will-you-have/ that's been recently active.

As for attachments, it's a personal preference thing that differs depending on the gun. I'm more of the accuracy guy myself, so I'll be employing a grip and an improved sight very often. Scopes are for bigger weapons (assault and light rifles), red dot sights for everything else.

Yep, let's use that one.
