Magazine and bottom metal compatibility

The various magazine configurations have me a bit confused...

I'm waiting on a stockys carbon stock for my 16 LWH. The original stock has the molded in magazine well, and uses the tabbed axis type magazines like these:

With the new stock will I need a new trigger guard along with the new bottom "metal":

And will my magazines be compatible, or do I need to change to this type:

Thanks all

The second link you posted, which is the bottom mag frame(plastic), is in deed the correct one for the current magazine you have. You would not need the one in The third link.

More than likely you would need a trigger guard to go along with it with the new stock, as the mag frame will not be molded in.

Boyds also has long and short action bottoms in metal for $77.00
