[Pic only] Four mode trigger assembly

I won't post the model until it's all done.Thanks to the following people for their models.ehsan's Trigger Assembly for Ak47AMSD'sBushmaster ACR - 223Here is some nonsense that perhaps no one will read.While I was building a new type of weapon, I realised that I could no longer just call someone else's modular trigger assembly as I had done before. So I set about building a new type of trigger assembly.And the assembly that you see here, it has four modes in total 0-1-2-30, which means safety, semi-automatic fire, double burst fire and full auto fire."Why not have a 0-1-30 three mode trigger assembly like most rifles on the market?" , because I read that a certain model of the AK-12 has a double shot burst firing feature. I'm sure you can see that all along my designs have been more Soviet oriented, so I still overcame many difficulties to design this double shot burst fire feature."So why not three-round burst fire?" I also noticed that there are several variants of the Kalashinikov rifle with a three-shot burst fire mechanism, some of which require an additional selector lever to switch between full-auto and burst fire modes (yes, I'm talking about the so-called "ROMANIAN AK74 - 3 SHOT BURST REPAIR SET ", which was used on the Polish Kbs wz. 1996 Beryl), or a version with only three burst shots and no full-auto function. I also referenced the AK-107's three-round burst firing mechanism and I have to say that it is really nice and the Soviets did a great job with very few parts. This mechanism was later modified and applied to the AK-12 rifle. But after much investigation, I made the present mechanism following another clever design I found. Another reason, this new weapon I am building, may not be suitable for three shot burst fire.Yes, you can see a lot of familiar features in this mechanism.The "smooth lines" of the hammer may remind you of the G3/MP5, the semi-automatic hook may remind you of the kalashinikov, and the implementation of a feature may remind you of the FN FNC ........The trigger assembly of the kalashinikov series of rifles is "simple and flat", the trigger assembly of the AR series of rifles is compact, and as the comparison chart shows, my mechanism is much more complex than Mr. Kalashinikov's design, and much larger. It is also larger than the modular trigger group of the AR rifle. The large hammer might make you think that my mechanism is intended for firing a 14.5mm or 23mm rifle.I also have an additional design point that has long been a problem for me with the Kalashinikov rifle in terms of the sequence of firing modes, the full auto mode is in between the safety and the semi-auto mode and when you are in danger you subconsciously flick the selector lever quickly, but the excessive force may cause you to select the semi-auto mode instead of the full auto mode. But on my mechanism you don't have to worry about that, just push the selector lever all the way down and dump your bullets on your opponent!
