I bought a complete H&R retro M16A1 lower. It wasn't cheap, but more reasonable than I expected.
I got the A3 Dissy upper from PSA, I planned on changing the upper and handguards. It has a mid length gas system to make it reliable. It's low profile and hidden really well.
Had handguards laying around and popped them on to see what it was going to look like.
The front sight pins were driven in by the Hulk. I opted to drive the gas tube pin out and slide the gas block forward then ease the tube out of the receiver.
The barrel was also tightened by the Hulk and I had to put a three foot tube on the wrench to remove the barrel nut. Swapping the receiver was a piece of cake and torquing back was no problem. Had to install the rear sight from a parts kit and the dust cover was also a kit.
I know it's black, but that will change soon.
A three prong flash hider is still on the way.
