Want M4 rail covers

I want some black M4 rail Corvers

i dont have any to sell but the bamboo type are my favorite. you can cut them down to whatever size you want and dremel down the rubber rail indents to fit any type of rail. also the rubber bamboo texture is great.
anything similar to this(they seem to be out of stock at alot of places) - http://www.strykeairsoft.com/shop/index.php?main_page=product_info&cPath=25_29&products_id=83

+1 with the bamboo covers
