Billet 80 Lower
The billet 80 lower is the easiest and most popular way to build an AR-15 at home, legally, unregistered. If you’re on the fence, here’s why you should do it: You don’t have to deal with waiting periods. You don’t have to stand in line at the gun counter for 45 minutes while your background check clears. You don’t have to pay FFL fees. You don’t have to choose between “this roll mark” and “that manufacturer” and higher prices.
Benefits of Machining a Billet Lower
Instead, you get to be the proud owner of your own, truly home-built black rifle. Pretty cool. But why a billet receiver? Why not cast, or forged? Billet 80% lowers are milled from aluminum bar stock, an extruded (and crazy strong) piece of raw 6061 T6 aluminum. If you’re seeking the perfect balance of weight and strength, this is the best choice. Billet aluminum can be cut into complex shapes, allowing for added features like a broached mag well and a one-piece, integrated trigger guard. If you want to place your own roll marks, mill some designs into your receiver, or generally work with fine lines, a billet lower will offer the best blank canvas.
