Careful with Duckbills there is a serious flaw in using them.
The design of the SKS that uses a fixed magazine is the bolt is designed so that the magazine can be opened and closed in any bolt position.
The duckbills mag will not allow the magazine to be dropped if the bolt is closed.
( note last round out the bolt will stay open and mag can be removed.)
So case in point, you end up with a misfire, and still have two round in the duckbill.
You cant eject the mag unless the bolt is open, but if you pull it back you could double feed
and ( BANG) could occur.
The SKS ( M&D) take AK magazines and have a bolt that allows it to be removed in any position.
Duckbill can be used and mags dropped any bolt position if , one shaves the bolt to do so.
But that is at your own risk, I have seen no reported issues shaving the bolt. But if one is going to use duckbills you will need three hands to clear a jam and then its dangerous.
