So I decided to build my second AR "platform" firearm. My fist was a rifle and now I am interested in building a pistol version. I don't wanna go through and pay for a SBR, so I have decided to go with a pistol instead. That way if needed, I can conceal carry it, I don't have to worry about anything when/if I travel... unless I am going to a restricted state. It will just be a nice PDW/pistol for range use..... maybe home defense if needed. Depending on how things go, I might get the SB15 also.
