He nor I am not aware if a bayonet lug can be made or added on? As I once years ago posted a converted mak90 to 56s and the guy said that a true conversion has the bayonet lug on it and some habe the cleaning rod. I am not sure how to accomplish this or the price. He converted the nhm91’s to where the lower hand guard has rails to add the bipod, so it doesn’t rest on the barrel which causes ****s to string us the barrel gets hit apparently. So, I don’t know if or how a lug could be added on. Just looking for potential fixes that aren’t expensive as he wants bayonets on his Ak’s. So if it can be done which bayonet would work best for the method used. Thanks for the info as I have an old friend who avoids computers like the plague. I have been helping him sell his stuff for years, no charge as he is a great old man. Which if anyone want an impossible to find Md arms 20rd 12ga Saiga/lynx mag I have one listed for him. He also wants to find a norinco sks d spiker or 56s spiker locally for cash if anyone can help(yes I know they are expensive).
