perfect training aid.

I have used these sets before and will buy more in the future. I teach an armorers course and had a few clear acrylic receivers made. I use these internal parts to show how the military version works compared to the average AR15. they make awesome informational training aids.

This is the same Sear as any Military Auto weapon. However. you will also need the 1/8 inch "Sear Pin" (same length as hammer or trigger pin.)
