I saw a post earlier on another board that got me thinking. So, I thought back to somewhere I read that some odd type of AK fired once when the trigger is pulled, then again when the trigger is released.
So, I thought that since that is 2 functions it seems to be legal. So, I began trying to come up with a design in my head for a mechanism for an AR-15 to perform a similar function.
Well, I came up with one. There are 2 problems I can think of off the top of my head after trying to visualize in my head the function of the mechanism.
1) It would require an M16 Hammer. But, since it would be semi-auto. and utilize both latches, then the M16 Hammer would in fact not be used solely in a MG. But, I wonder what the ATF would think.
2) An AR-15 Hammer is missing the Auto Sear Latch which is what my design would use to lock the hammer back after firing. When, the trigger is released, the latch would be disengaged from the Auto Sear latch allowing the hammer to release. But, if an AR-15 hammer were used, there would be nothing to catch the hammer and lock it back. Therefore it would slam-fire a 2 round burst. I think this would be the part that would kill it legally.
3) I thought about making the mechanism and sending it to the Tech Branch for an opinion. But, I began thinking if they ruled it illegal, then they might throw me in Club Fed.
What is your opinion ?
