I disclosed on my post that it was a "K" version. Unfortunately there wasn't a "K" on their website to reference it. I accept partial responsibility as I should have called before purchasing. My biggest reason for the post was a lack of response from Customer Service. Right, wrong or indifferent, a response was warranted.It was advertised as a Banish 22K-V2, and that is what we all received as the BOGO. Version 2 of the Banish 22 suppressor, smaller and lighter. Yes, it doesn't reduce the sound as much as the Banish 22, but it is a lot smaller and more convenient. Just because you can't read and interpret something doesn't mean that you can diss a company that delivers on what it advertises.
