(6,942 posts)Bump-fire stocks exist in order to make bump-fire moderately controllable. Yes, you can hook your thumb in your belt loop and make some standard-stocked semi-autos bump-fire that way. The notion that anybody would use this as anything other than a range trick is ludicrous. It's inaccurate and prone to jams.
What you're talking about with the SKS is not bump-fire. It's slam-fire, caused by the free-floating firing pin. If it's caused by soft primers, the rifle will probably just fire a short burst because you will release the trigger when it happens. If it is caused by a seized firing pin, it may empty the magazine even if you release the trigger.
Slam-fire is completely different from bump-fire. It is not controllable. You never know when and if it will happen. If your SKS does this, get it fixed as soon as you can, or you risk an out-of-battery detonation, potentially damaging your rifle and injuring yourself.
The only usable, controllable form of bump-fire is with a bump-fire stock -- as in the videos you posted -- and that has its drawbacks too. The ATF has decided that it's not an issue. You seem to have a problem with it, but you haven't convincingly articulated it.
