What is your question exactly?
All you keep saying is "I have an ak105 what is compatible with it"
I dunno 6mm bb's are compatible with it
ak magazines are compatible with it
silicone oil is compatible with it
an ak sling is compatible with it
it has a v3 gearbox so most tm compatible internals would be compatible
but again all you say is "what is compatible"
if you don't show that you have at least tried to help yourself then people are not going to help you
making 4 threads all relating to the same subject is just spamming and shows that you are impatient as well as lazy
