Armorers, rejoice! Thanks to the consideration of today’s small arms manufacturers, you don’t have to order each pin spring and washer that you’ll need to upgrade or rebuild an AR-15. Instead, you can invest in kits with all the high-quality standard parts necessary to upgrade a rifle or build one from scratch. At the same time, a kit like the Aero Precision Lower Parts Assembly for an AR-15 won’t come with the parts you might prefer to order individually to fit your preferences. It’s a lower parts kit without a trigger or grip, which will allow you to pick out these parts on your own while still setting you up with all the other parts you want.
