bushman had the market for this stuff... he is no longer making it. mold99 on ebay currently has a good selection of shrouds and a fake supressor, as well as a alum. trigger, mag release and charging handle. very good quality by the way. as far as rail systems go no one has filled that gap in the market (that i am aware of). i would suggest drilling your own holes in a rail. thats what i had to do. hope this info helps
