This topic should be of particular interest to 3-Gun competitors. If BATFE finds that the Saiga and similar guns don't meet the sporting purposes test, then they can be banned for importation. That means either they won't be available, or they'll cost a lot more because they won't be bringing new ones in.
In the past, BATFE has only considered this question about once every decade. If you care about this, please submit official comments to the agency. You can submit them by fax or email. I believe a professional, well-drafted fax would be the most persuasive, but every positive comment helps.
Attached is a letter I sent regarding this issue. Feel free to PM or email me if you have any questions.
