Re: AR-STOCKS
Yes...they'll fit. Will they hold up...NO!
There is a reason that they are marketed as airsoft components. Like folks have already said, stick to reputable retailers and avoid eBay. If you must use eBay, you do so at your own peril. At a minimum, if you insist on going that route, I would ask very specific questions, ask for pictures and other documentation to prove that what is being offered for sale is the genuine article and not airsoft $H!T. Even then...it is a crap shoot with some of the disreputable folks selling anything and everything on there these days.
