I've been referred to this shop by a friend. But it has changed since! For the worst, no doubt. The owner is probably a very sick person for now. Paranoid about the new president, rude with young customers. If you are a foreigner - forget about this place. He will run from you behind his special bulletproof counter and start to repeat only one phrase: "You annoying me!". Keeping his hand on his CCW gun untill you leave. He has refused even transfer service. Whatever. I've found his selection poor, obsolete, and overpriced even for used things. So sad that this the only ammo retail place I can walk in from home.
Pros: Good East Bay location, exotic building.
Cons: Poor selection. Probably crazy owner.
