When I first started building I got my first lower from rooftop have always loved what he sells and supports his lower is just as good if not better then lowers that cost twice as much I ordered three and if I had more money I’d order a dozen more.

Very high quality lower, very tight fitting with my Geissele 11.5” URGI upper. Zero movement or slop. Couldn’t be happier with it. Rooftop got it to me super fast too… as usual! Thanks Sol!
