Soooo....... I have never here pulled the trigger and bought an AR. Just don't want to pay the price for it. After all it wouldn't be a rifle I "need". So I am thinking if building an AR this winter to save cost and give me something to do during the sucky winter weather. I don't know where to start on purchase. I do know I want to start from scratch. Stripped lower and go from there just don't know what the difference in all kits would be. I will go with an aluminum lower not a polymer.
