What in the world are we arguing about here. Who's AK is better? They all rock!

Now...if your friend had a WASR and not a saiga he wouldnt have to be tapping the trunnion in the first place!

+1 That's one point I can't argue

 

Also, why does it matter what is in your AK? And why do you have to "re-build" it yourself to figure it out? I get the comfort of knowing my AR-15s have Magpul LPKs, BCM uppers, BCM BCGs, DD rails, etc. But given the AK's operating and design tolerances, is it really that important? (serious question, not trying to be snarky)

In and of itself, is it worth $100? No. You can buy a WASR and still take it apart to know it inside and out. It's not essential, but it is a benefit.....certainly not a negative aspect.
