Does anyone make a 10 round 450 Bushmaster magazine? I'm finding five and seven round magazines, but no ten rounders.

Also, can you convert a 30 round 5.56 magazine to work with 450 Bushmaster?

Thanks.

As I recall, they make a drop in follower for .450 Bushmaster (and .50 Beowulf) to convert 30 round USGI to hold 13 rounds of .450

I know some guys that used blocks (or pins) to reduce that to 10 rounds for the banned states.

Here are a couple examples. There are cheaper ones available

Thanks guys. I think my friend is chasing the Wifflepoof on this one.
