Good question! It may and it may not. Regardless it would be extremely unsafe as there could be out of battery detonations of the cartridge. As soon as the bolt carrier passed the hammer on the way back froward, the hammer would start dropping and follow the bolt home. Who knows if it would even ignite the cardtridge, and if it did... the bolt may or may not be fully locked up. Full auto AK trigger groups have another component in them called the auto sear. This component only allows the hammer to drop again once the bolt is fully locked into battery. This also reduced the rate of fire significantly to make full auto fire more controllable. This goes without saying, but removing the disconnector from a semi auto AK trigger group would be extremely stupid, unsafe, and illegal if it did end up in a condition where the rifle could fire "full auto."

AK triggers smooth themselves out pretty well. This takes it a step beyond that. For those of us that like tinkering, want the most performance out of our triggers, or don't want to wait for it to smooth itself out.

The days of polishing the trigger surfaces by shooting are far gone. The metal used is alloy and maybe even surface hardened. That with the combination of cartridge prices makes it quite difficult task. Plus having the trigger feel change as it is being broken in during use is not the best if you really want to know your trigger.

@@ImNoBSINGWell said! Couldn't agree more. Shooting it will smooth it but never polish it. The finishes of the two metals rubbing together are not fine enought to ever get the finish I have put on them. Why wait a few hundred rounds (and a few hundred dollars) when I can get a better result with 20 minutes of my time and no cost?

@@ImNoBSING That's not true. I've gotten new firearms that smoothened out significantly from dry firing and racking the slide and/or from shooting them. Besides, you don't just buy ammo and shoot it just to smooth out your action. You buy ammo and shoot, because you want to. It costs money to buy ammo and go shooting at the range anyways. Smoothing out the action is just a bonus. If you buy a new gun (like a handgun with a rough Black Nitride finish), you can rack the slide and pull the trigger on it many times and it can smooth out a whole lot. The difference can be drastic sometimes (and Black Nitride is immensely Hard stuff). It may not smooth out the parts as nice as it would from shooting, but it saves a lot of time and money if you want to conserve ammo.

@@dltz It's not very different than polishing though really. It just polishes (or hones) the parts exactly where they make contact and like polishing it "flattens" and smooths out those areas. If you don't have the money to go shooting, racking the slide (or bolt) many times works almost as well. I've seen some extremely rough actions smooth out from shooting and/or from just racking... and triggers also from dry firing. I just recommend that if a person wants to smooth out their action like that, then don't use grease on the sliding parts before that, because it can stop that smoothing from happening. That CV-2 grease is some pretty amazing stuff too. I would never put it on a gun that needs to be "broken in", because it reduces wear so well that your gun will never get broken in with it. Can make some of the roughest actions feel smooth like glass. Started using it on the slides/rails and the barrel wherever it makes contact with the slide and/or locking block (or lug/cam/pin depending on the gun) After my long rant... I think you're both right in the fact that nothing is better than actually polishing the parts though. I just always thought AK's were rough shooting guns anyways. I know they make higher end triggers for them... but I've rarely ever seen anyone have an nice aftermarket AK trigger and/or a polished one. I think it's pretty recent that people started buying the nicer AK models. (but that could just be ignorance on my part).
