M4/AR15 crane stock adjustment peice with retaining nut.

This peice/peices are for the cranestock adjustment for the standard ar15/m4 and other compatible crane stocks. These ARE NOT the correct scale at the moment and will take a little figuring out to be correct. I will post the actual sized ones here soon once I have the scaling worked out. Both for realsteel and airsoft alike. If you have any questions comment or pm me. Check out my other airsoft and gun related designs!
