CB, I think if you look at the Ilion Satisfaction poll sticky, you'll see those that have ordered accessory barrels lately have been very happy with the products, some have come back in about a month, just depends on what you order and if they have it in stock when they get your frame. I'd call and ask when you're ready to order and have them check inventory, the bull barrels will be the most consistently accurate, but if they can give you the number of barrels available at the time you call, order the one they have the most of, that will give you a better chance of it being in stock when they get to your frame as they do them first come, first serve, they may have it when you call, but it could be out of stock later. Fees are listed on the order form in the FAQs and Help sticky, $15 fitting per barrel, $15 return shipping per frame you send in, toll free 866-776-9292. Another member posted recently that the shipping fee has increased to $18, they also charge sales tax. Some members have been charged other fees for proofing, but those recent orders have only been charged fitting, shipping and sales tax.
