The stock on my new m70 npap is not angled down very much. You practically have to jam your cheek against the stock to look down the sights, which causes some bruises and uncomfortableness. I was thinking about buying a new stock for it. I saw a tapco t6 adjustable stock for the m70 for 50$, which was cheap compared to others I found. Does anyone know if this is a good stock or if it is difficult to install?
