Notice the quotations.
I have been set on buying a Saiga 12 to slap a bumpfire stock on until I ran across this video of some guys with a saiga 410 Link: shooting saiga 410 full auto - YouTube
I'd have to say I am in love with this idea. Here's my reasons why.
shotgun ammo is still cheap.
a 410 is MUCH more controllable than a Saiga 12 with a bump fire stock on it
Also 30 round drums are only 99$ while 30 rounders for the 12 run 200-300$.
