I have a boggle im hoping ya'all can help me with. Should i build a AR pistol or a AR rifle. I have built a rifle 16in barrel once before. This time if i go rifle i would like to try my hand at a 20in barrel and go for accuracy. On the other hand i think a AR pistol might be rather fun, get the arm brace and all. As it stands the pistol will be a extra $30 tacked on to the final cost of the parts i found. I alrady picked up a Anderson lower and a DPMS LPK. I still have a left over stock from my last AR rifle build to save some cash, if i go the rifle route.
