I was thinking this too.. How is this thread not shut down? A semi-auto with removable mag, bayo lug and not permanently removed threads... Seems like un unregistered AW to me. So who's making $500 here?"I own an AR-15! When I was an Electrician Apprentice about ten years ago, I bought a Pre-Sunset Ban..."
Now you say its your fathers? which is it...
This comes across as a troll. If you are LEO and privileged my apologies LOL
ETA: I just got a Wilson Combat LPK. They do not come with FCG or grip, $60, unbeatable quality.
