When millions of recently armed Americans will have to go up against a superior armed and supplied police state they may need something more than just their numbers and bad breath.

Myself I would think that in the near future we will see people taking a 3D printer to make all the sear parts in the AR that allow a conversion to 3 round burst or full auto.

Though these may be resin parts they can be plugs for molds that in turn can be used for cast metal, or copied for those that have mills or lathes.

Either way the 3D printer will be like giving the Confederate Army AK 47 rifles against single shot rifles of the Union Army.

Waste of ammo.

Remember, when TSHTF the purpose of your civilian weapon will be to obtain a military weapon. This is the lesson of countless revolutions and insurgencies.

That said, you can't drop an M16 fire control group into an AR15 receiver. There are several key differences that make it difficult to militarize an AR even with the proper parts. If someone wants to provide a REALLY valuable service, they could post a printable M16 receiver. Or better yet a printable M14 receiver!
