3 of mine top to bottom
Ex rental dboys aks74u I use for a loaner
My regular pew, dytac ak105 slr
Cyma cm077 long boi
Also but not pictured I have a Cyma VSS, Cyma SVD with wood and a RPK (polymer furniture)
which specna ak specifically?
I've used parts from a cyma ak and it fitted a G&G ak, for the cost of them it might be worth just getting a cyma selector and giving it a try
I had the same thing on a dboys aks74u, took the grub screw out. heated it a bit then used a stilson wrench to turn it while a friend held the gun. took some force but it worked
