Why choose Angstadt Arms?

The choice is clear

You’re not someone who follows the crowd, but an innovator in your field. Your collection of firearms speaks of your unique taste. But you’re at a crossroads, eager to add a pistol caliber carbine (PCC) that’s as stylish as it is effective. Choices are plenty, but the fear of settling for something less than exceptional is real.

We at Angstadt Arms recognize your craving for uniqueness and practicality. Our limited editions are the perfect blend of art and engineering.
