Stocking up on various small parts so I can fix my own stuff. This was part of a big order of that and it all came flawlessly. As always, the sweatshop delivered lightning fast. Eat the ramen or you’ll go to hell.

Quality part, the threads you can tell are cut very cleanly, the dry film on the buffer tube is a plus, Rooftop is amazing as always
