True 5 or 10 round magazine for AR-15

Is there such a thing?
It would have to sit flush with the mag well just like the 5 rnd M1A mags.

You bet it does! They are most often used with Highpower Match Rifle competitors. If no one whips out an answer quick-like, I'll get it for you.

The answer I have received is to get the 8-10 round mags with the plastic extension and remove the extension.
