Just curious as to the differences between single and double hook kits. Are the two interchangable into any AK? Does one have advantages over the other?

If not trying to go 922r compliant is it worth the time and $30 to upgrade to a G2 trigger? And thus have to go 922r compliant? If your AK is not suffering from trigger slap that is.

A local GS has both kits in stock and I really like supporting the small town shop vs online. I have found very little info on the G2 kit in a single stack Romak 99 AK variant.

Thanks guys!
