mp5 sling and stock

[dazzer306]

Hi

Need some help locating a 3 point battery sling and a rear folding stock for mp5. The sling I've seen was on a player's mp5 wbere the battery was in the sling as he had an ICS butt stock no battery space on them eithier. As for the stock looked but cant seem to find one. Any help would be great thanks
