Understood about keeping the thread true...I just stated my opinion about the lower..I have used and shot 3 different spikes built ar's and know that they function 100% lion the insides, now that I know that...I.move to my next build...which happens to be an aesthetic one! One that functions a well as a no frills ar and looks like a refined beast...that's where I am headed.
Post pics when it's done to show it off a little bit. I'm curious to see how it comes out.
