Although it seems the Bureau of Alcohol Tobacco Firearms Explosives and Fun (ATF) a little late Snowlakes in Hell let us know they finally released their shotgun study [PDF]. Surprisingly it seems Saigas may be safe.
There is some stupid shit in there. For example exhibit four talks about integrated rails. If your rail runs along the top of the shotgun it’s “for sporting purposes” while rails located anywhere else are apparently only for murdering people with our side mounted flashlight (flashlights are also an item on the “bad things” list). Forward pistol grips are apparently evil as are those horrible magazines that can store an arbitrarily high number of rounds (the ATF chose five to be the number of rounds useful for “sporting purposes”). Oh and mounts for grenade launchers are also a no-no.
Basically the list contains a ton of stupid shit, about what you expect from a government agency that only exists to bad things that are fun. Thankfully nothing on that list specifically prohibits the Saiga shotgun (it’s imported with a five round magazine).
