AR-10 Lower Parts and Kits
Your AR-10 lower parts kit is a crucial component of your build. It’s also where most home builders get mixed up, and end up with incompatible parts! Generally, standard AR-15 fire control groups and safeties work the same, but takedown pins, magazine releases, and bolt catches can vary in fit for your lower receiver.

Your AR-10 lower parts kit is a crucial component of your build. It’s also where most home builders get mixed up, and end up with incompatible parts! Generally, standard AR-15 fire control groups and safeties work the same, but takedown pins, magazine releases, and bolt catches can vary in fit for your lower receiver.
Generally, we say to stick with the same brand of your lower receiver when choosing an AR-10 lower parts kit. If you’re not sure what you need, feel free to reach out, and we’ll get you on the right path!
