The Best AR-15 Lower Parts Kits in 2023

The Russians have a saying – “a man is not a man until he has broken a horse, fathered a child, and built a house.” I’d add “and built an AR-15” to that list. It’s a bit of a right of passage for every firearm enthusiast — one day you’ll decide it’s time to build an AR.

You’ll spend hours pouring over reviews, diving into the forums and /r/guns, agonising over the nuances of BCM vs LWRC vs Aero, with the goal of nailing the ideal upper. Be it class 5.56, .300BLK, or something more exotic, you’ll pair it with the perfect custom, stripped lower.

Of course, that new Bravo Company lower isn’t much more than an expensive doorstop without all the bits that help it come to life.

For new builders, sorting through the various kit options, colors, triggers, & variety of furniture can be daunting. Rest assured – with just a little guidance, you’ll be off to the range enjoying your new hand-built AR in no time. This article is part of our ongoing Guide to Everything AR.
