5 round STANAG pattern magazines

[medvedqc]

my mp II came with a mag 5 rounds that is still sealed dont see the use in the future anyway ...

A true 5-rounder that doesn't stick out from the magazine well might be more convenient prone or from the bench, but you'd want grips on the bottom so you could reach up the magwell and tug when necessary.

30-rounders pinned to 5 are just grotesque.

Lancer also makes 5 rounders.
