Hey guys, I got several M17s that I decided to upgrade to M40s. I've replaced most of them so I don't need the 17s anymore. I haven't looked at them in a while so I will be inspecting them and function checking them before they are sent. A select few of them have been repaired, the better quality ones will go first. $40 each with the canvas bag, Shipping to Conus included. I sold all my extra filters for these, but they are available online. ***I have these stored in a storage facility that I have access to on Friday, Saturday, and Sundays only. Please keep this in mind for shipping purposes.***
