Thinking of buying a stripped stag lower from Jkiser. $99 http://www.ar15.com/forums/topic.html?b=7&f=125&t=277221 That parts kit. Need Help with the upper and stock. I would prefer the upper would be left handed (STAG) Needs to have a brake not a hider. Also needs to have a fixed stock. I want to put optics on it so i am going to go with a flat top with a detach handle.
