Good upgraded parts - Geissele Ultra Duty Lower Parts Kit

Christopher Peterson's Review of Geissele Ultra Duty Lower Parts Kit
Definitely better than the stock parts on an AR build. Make sure you know what you are doing and watch YouTube videos before install, some pieces look almost the same, it’s important to not mix them up and use the right springs and pins for correct things. Bolt release is nice.
