=Explanation=
-A way to customize weapons to resemble legendary classics that we all got used to.
=Positive matters=
-Weapons equipped with retro attachments would increase experience gained per kill.
-The experience increase refers to both player account level and weapon level. (single % per piece and up 10% for the whole kit for weapon XP, as for character XP it can be achieved only with a whole kit assembled)
=Balancing=
-To balance the experience gain, other stats would be either neutral or negative in nature as they would be in practice decreasing effectiveness of the weapon,
due to older and outdated equipment being used.
-Furthermore to balance the experience gain, some attachment options would be limited (due to lack of attaching options).
=Acquirement=
-Attachments would start to become available at low/middle levels.
=Examples=
-Thumbnail included are some examples of such attachments ,that being the classic vietnam-era ''pencil'' furniture on a M16A1 or the M14 stock from wich the EBR is derived as well as the good ol' folder wooden AK 47. (Examples and combinations are possibly endless).
