My DD progression.

Bought it from a friend at the top. Removed the fore grip and flashlight combo thing, had a sure fire that fit, but didn’t like the look.

Added angled fore grip. Middle.

Removed the iron sights and handle, new gas block. Added Vortex optic.

Overall work so far: Paid $1K for the rifle, 4 mags and 200 rounds of .223. Angled grip was free. Gunsmith did the handle, iron sights and new block for $65. Optic was $125. Ready to go!
