      We sincerely apologize for the shipping delays. The covid panic buying in March of 2020 was something we had never experienced before. Before that orders were going out within 1-3 days. Since then we have completely restructured our shipping department so this never happens again.

    Wrench was originally received in used / damaged condition. B. King’s support staff promptly responded to my inquiry and provided postage to return damaged wrench and then quickly re-sent a new wrench to me. It would have been nice if they could have sent the new wrench before receiving the return, but I understand that they need to protect themselves against scammers. At the end of the day, I didn’t need the barrel wrench urgently and I got a new one in about 1 week. I will not hesitate to order from B King’s for all my firearms needs. Cheers!
