Well Im going to be 18 in 2 months and some days. I will finally be able to own a gun of my own. Im really looking at getting an ar 15, but Im not sure what to get. From the reading I have done there is not much difference in the Tac sol and Spikes. It appears more of pick what you think looks better. and I cant find much info about the wilson combat upper. I need a flat top with no front sight post because I play to run it with a EO tech or acog, which I already have both. I know I could co witness but I have never looked down a rifle that was but i dont think i would like. O and where does the wilson combat upper stand compared to the spikes or tac sol.
