Replaces the stock MP5A5 and MP5SD6 with equivalents from RobertHammer's SMG pack. Optionally you can replace the sounds too.
This is a pure client-side modification. The players you play with online will not be affected by this addon in any way, it does not change damage values, zoom levels or anything else than the model itself.
For players who do not have this addon installed you will appear to hold the original models, while you will see them holding the RH pack's equivalent. The same rule applies for any weapons lying on the ground - you will see them as RH weapons, others will see them as original weapons.
