Re: Upgrades for AK-47 Mac 90?
+1 for an Ultimak rail gas tube. Maybe put some sort of optic like an Eotech on it for quicker target acquisition. If your into iron sights I put a pair of meprolight tritium night sights on my Arsenal and I have no complaints. As far as trigger upgrades go the only input I have is stay away from a Jard adustable trigger, they are complete junk. I guess I dont touch AK trigger groups they are not a precision rifle but to each his own. I think the biggest question is, how much do you want to spend?
