I had the idea to tack weld the fins for the lug, but then I would need to thread the barrel and put on a brake, or at least get a pin on brake.

But earlier I was looking at the M91 Mosin Nagant bayonet and figured that if I made a bottom cut and widened up the top groove and the side groove then I could make it fit my AK. Lets be honest in a SHTF situation the Mosin bayonet would be way more effective than the standard AKM bayonet in close combat.

So what do you fine fellows think? Possible?
