    Fast/Awesome Product

    Yes, it's just a castle nut, but it is nicely finished and well designed. It came much faster than I expected. Before my castle nut wrench that I ordered prior.

    Bravo makes fantastic products. I don't think any AR guy will say otherwise. Prices are also reasonable.

    Thanks guys. I'll be back.
