Novelty item, but it's a nice touch - Geissele Ultra Duty Mag Release Button

The regular mag release buttons that come in every other LPK have worked just fine in my rifles for years.
This one is a novelty item. When used with the Ultra Duty Checkered Stainless Takedown Pins, and the Maritime Bolt Catch, it enhances the aesthetic congruence of the overall setup. The checkering is nice and tactile, but nothing super duper stellar. Not like it's head-and-shoulders superior to the normal vanilla part.
Not necessary. Just nice to have.
