I've been looking at some of the aftermarket chassis for the m14/m1a rifle. don't get me wrong, I know that you get what you pay for. so the chassis are top notch quality, made of either aluminum or fiberglass. I was looking into the archangel stock, but its a composite plastic similar to the SAI stocks. I was considering on just fabricating my own collapisble buttstock. Has this been done? I couldn't really find anything on it. And I was curious as well if its recommended to do that with a fiberglass or wooden stock. Does anyone has any experience or advice for such a project?
