Custom SKS, AK influences.

I missed one picture

So you've managed to get your rifle to fire. Now, what stops it from firing?

You have removed both of the disconnectors from the FCG, and from the looks of things the AR-15 trigger components don't have any either. I don't see anything stopping the trigger from dropping the hammer on an open bolt - meaning the hammer would follow the bolt when you returned it, holding the firing pin fully forward out of the bolt face - which at best would result in a chambered round and a dead trigger, at middling worst an unexpected discharge when chambering a round, and at worst an out-of-battery detonation.

There is a reason the Russians went back to the SKS FCG and added a rebound disconnector.

You need to look at the pictures again, I have two photos that clearly show the AR disconnector functioning properly. the trigger drops the hammer and the disconnector grabs it on the recoil. When the trigger is released the sear engages the hammer and functions as the trigger should. Spend a little more time looking at what I have before you claim i have "removed both of the disconnectors". I have cycled the bolt with this trigger in place and it feels exactly like my AR.

I will repost these here

I stand corrected. The AR-15 trigger group has a rebound disconnector, so you have replaced that functionality at least. As for the lack of a bolt disconnector, this is clearly an aesthetic build to which function is secondary, so I'm sure you will be very happy with the result. I'm interested to see what you come up with for a safety, though. Keep posting updates!

Okay for one this is not an aesthetic build, I intend to use this rifle, and wanted something more comfortable then the stock sks or the tapco stocks, i needed to have the trigger and more importantly pistol grip moved forward. I also wanted a more user friendly mag release, so I went with the AK style (which hasnt yet arrived)

I dont understand what you think is wrong with this trigger setup? It functions EXACTLY as it does in an AR15. What is this "Bolt Disconnector" you are referring to? with the bolt back and the trigger pulled the AR disconnector grabs the hammer. if you release the bolt the hammer is still retained by the disconnector. I am not understanding what you see unreliable in this setup? it works flawlessly in an AR, why is it all of a sudden going to be problematic?

As far as making more i am sorry but i am not interested, for 2 reasons. One it is alot of work and it is not very nice looking it would require alot more time to look "good" and i wouldn't sell someone something looking like this does, and second for the safety reason, I do not want to be held accountable for someone using this and having a failure resulting in an injury or worse.

thanks for the interest. Not trying to be a D*** to you WmMcLeod, just not understanding where your coming from.
 
My AK mag release showed up today. I know the welds are not all that pretty, but I plan to clean everything up a bit once i know for sure it will function properly. At this point i am ready to test fire it and see how it works. I have 2 ideas for a safety, one is an AK style lever on the side of the stock that would stop the AR trigger from moving internally, the other is a Cross Bolt safety I removed from an old paintball gun that I may mount behind the trigger. Both would get the job done but the AK style would fit the build better. I also added a small piece of metal behind the trigger guard to level out the AK grip a bit.

The bolt disconnector is the long arm that runs the length of the trigger group and sticks up just in front of the hammer. The bolt engages that upper arm when it tilts and locks, pushing the armiture down. The bolt disconnector performs 3 functions.
- It locks out the hammer until the bolt is in battery.
- it engages the trigger bar to the sear only when the bolt is in battery
- when the hammer is dropped, a tab on the backside of the hammer pushes the bolt disconnector lower and disengages the trigger bar.
I hope this makes sense. Good luck with the test shoot!
 
i have a small update, not so good news yet. I had it to the range and fired 11 rounds of those 11, 4 were light primer strikes. (we put them in another SKS to be sure they wern't bad rounds) The stock did not break, and felt very comfortable when fireing. When I got it back home I noticed that the hammer spring had bent down alot. to the point it had about half of the tension on it that it had when first assembled. so at this time I am on the search for a new spring. I also may look at cutting the hammer down to create less drag on the hammer, however I am concerned that the hammer may then not have the necessary mass for proper primer ignition.

I haven't done anything to it since I fired it as I have been busy working on my Unimog project now that the weather is getting better. I will post an update when I locate a new spring and test fire it again.

On a side note, my promag magazines all functioned nicely!
