"Third world type rifle"?
The original design was certainly not conceived of in a third world nation.Not to defend Russia,and certainly not to defend the Soviet Empire-as they were and are many undesirable things,but 'third world' they were and right now are not.
The people of the third world that use AK type rifles would just as soon use any other type rifle they could get their hands on,but it just so happens that AKs are the most prolific rifle ever,so they are everywhere.Besides helping many industrially-capable Communist-friendly nations to produce their own variants,when the Soviet Union upgraded their arsenal from the AKM 7.62x39 to the AK-74 5.45x39,they literally hemorrhaged AKMs onto the world market.
Alot of what is over there in those third world s**t holes that couldnt actually produce their own versions for lack of technological and industrial ability comes directly from Soviet military surplus.
And just because a rifle is surplus,does not make it a 'third world' rifle.
You can still find k98s and Enfeild rifles in the hands of third worlders and those aren't 'third world rifles' either-but are some of the finest infantry rifles ever fielded.
Some of the most industrially and economically advanced nations in the world have even adopted the AK in some variant or other as well,just look at the Galil and Valmet rifles.
And the AK design continues to be improved upon to this day,with the AK 107 and 108 rifles that feature an advanced 'counter-mass' gas system that,IMHO,bests both the direct impingement system of the AR design and the piston system of the original AK design.
Rather than the AK designers adopting a gas impingement type system and compromising the reliability of their design,or the often encountered gas piston system being adopted for AR type rifles compromising its superior controllability-this 'counter mass' system is truly the best of both worlds.
It keeps the superior reliability of the piston system by eliminating the 'craps where it eats' problems of direct impingement found in the AR, while reducing its major drawback-the hindrance in accuracy of fully automatic fire because of the recoil impulse of having a heavy bolt group slamming around,which the AR designs gas impingement did not have.
This is a technological innovation you can hardly expect to come from a third world nation's ordnance and arms designers.

..........counter-mass to compensate the recoil impulse, generated by massive bolt group, slamming against the receiver in its rearmost and forward-most position during the reloading cycle. The counter-mass is linked with second gas piston and moves in opposite direction to bolt group. Synchronization is achieved using a simple rack and pinion system. In this system, only the impulse of the fired cartridge is transferred to the receiver, and through the buttstock to the shoulder of the shooter. The impulses of the heavy and fast-moving bolt group are compensated by the counter-mass, and do not affect the shooting, unlike the AK where the moving bolt group produces a lot of additional recoil and vibration.
There is absolutely nothing foolish about owning an AK and putting money into it to make it a better shooter for you.
In fact,that looks like a pretty good setup you have there,and as I have a SAR-1 myself and have been considering new stocks I am taking note of yours.
