I dont know much about rifles ,Im just getting into them. I have always been a handgun guy. With that said I am about to purchase my first AR,I want to put a handgrip and a flashlight on my rifle. Can you put a rail on the stock foregrip or do you need to remove the stock foregrip and put on a differnt one to do this? Also how hard is it to change the stock? Sorry for all the noob questions but Im trying to learn. TIA Wanna kill these ads? We can help!
