I’m gathering parts for a project and there is a bewildering array of lower parts available. Many are aluminum, some are titanium. I’d like to possibly substitute some parts but don’t want to downgrade in materials.
What materials are used in standard lower parts? Specifically I’m thinking of the castle nut, end plate, safety selector, bolt catch, magazine release, and pivot and takedown pins.
If they are not aluminum, does using aluminum cause issues with durability? If staking the end plate to hold the castle nut, is the dimpling less effective? Would pivot and takedown pins wear out?
