Finish is a little rough but it works great - Luth-AR Slick Side A1 Stripped Upper Receiver

I had a buddy who I bought one of these off of. It worked fine for my A1 retro build. The finish is a bit rough, but everything is in spec and works fine. Honestly, the best part is that these are actually in stock so I'm ordering one for a different build.

Del-ton A2s, Brownells, retro rifles, etc. Everywhere but here is out of stock. So yeah, this is kinda your only way to go if you want to get a carry handle upper at the moment. I'd recommend getting a cerakote job done to make everything on your gun smooth.
