Can you put a HK upper on an AR-15 lower?
Super Moderator. The thing to keep in mind with any AR15/M16 lower to which you attach an HK416 upper is that you MUST have a hammer that has the proper profile to hit the firing pin safety. The M16 hammer should already be able to do this. Some AR15 hammers have a profile which is not “tall” enough to do this.

Can you put an AR pistol upper on any lower?

Can I sell an AR-15 that I built?
Proving the original intent of your AR-15 build The safest way to legally sell your home-built AR-15 or firearm is to make sure you can prove, before the sale (if ever necessary), that your original intent was not to manufacture your AR-15 just so you could sell or transfer it to another individual.
