@Wavey_Gravey @SBoardley if you want the Car-15 stock with the vertical lines on the side B5 Systems have them as well as Brownells and Brownells have the Pad. They'll be your best bet for new stuff. I've built two Car-15's one with pad and one without, you get two different style of Car-15 stocks the smooth one and the one with vertical lines lines, theirs more too it like material etc...
MadDog make a Car-15 Stock with ButtPad that you can get from Sixmm for about £25 (not including postage)
Id get the Skinny Hand Guard from Brownells, that's where I got mine from.
