    First time customer, ordered the Bond Arms 4.25 polished barrel in 45 Colt/410. My order was shipped quickly and received in just a few days. Great service, prices and staff, was really surprised at free shipping and no tax. Would highly recommend BuckSnort Outfitters to anyone looking for a great deal.

    Ordered my barrel on Wednesday and received it on Saturday took it out today and shot it was surprised at how well it handled, I had ordered the oversized grips a month ago in anticipation of getting a larger bore barrel I have large hands and the larger grips help me control The recoil of the 45 caliber round and the 3 in 410 shell I'm very pleased for this purchase and with bucksnort the service they give is excellent I'd recommend bucksnort and Bond derringers I also have it in 357/38 caliber

    4.25 "327 Federal Magnum

    It's a great round. Any weapon chambered in this now gives you 5 different loads you can use. It's backward compatible. Item did have a small nick on the right side. But hell it's a tool.

    Didn’t know what to expect with 10mm in a small gun, was very manageable to shoot. BuckSnort gets 5 stars as usual

    I just love this gun. It gives me the ability to change lengths and calibers of barrel without replacing the body, How cool is that?

    The company is by far one of the best to deal with. They took my request and filled my order over a month later when pride came in to them. Great folks

    Hello! I don't know if you are able to do this, but if you can I would like to be notified if you get a Bond Arms 22 magnum barrel in stock. It doesn't matter to me the finish. I would like the barrel to be 4 inches or longer. Thank you for any assistance with the barrel. Tom Pierce
