- For any non-integer magazine values the magazine size is simply rounded to the nearest whole number. For example, a Dual Decurion modded with a max rank Magazine Extension will have a calculated magazine size of 32 × (1 + 60%) = 51.2, which will simply round to 51.
- All arch-guns use their entire ammunition reserve as the magazine that regenerates over time, thus acting as both an increase in magazine capacity as well as maximum ammunition capacity.
- Does not increase reload rate. Due to this, unlike magazine capacity mods for non-Archwing weapons, Magazine Extension does not increase sustained DPS.
