📋 About This Mod
This patch aims to make Combined Arms compatible with calibers from Caliber Complex, by removing the ones added by Combined arms and using Caliber Complex ammunition instead. Additionally, some calibers were added or removed to certain weapons for realism.
Calibers replaced/removed include:
. 300 Blackout (removed)
. 338 Lapua Magnum
. 357 Magnum
. 50 Beowulf
20mm Vulcan (removed)
25mm Grenade (removed)
7. 62x25mm Tokarev
7. 62x39mm Soviet
7. 62x51mm NATO
7. 62x54 Rimmed
9x19mm Parabellum
9x39mm SP-5
. 416 Barrett does not have a Caliber Complex counterpart, and was therefore left alone.
*. 40 Smith and Wesson was added to the M9 Beretta in place of 10mm and . 357 Sig
A compatibility patch that makes Combined Arms weapons work with Caliber Complex ammunition, plus a few realism tweaks. With 177 endorsements and over 6,000 downloads, it's a niche but proven fix for players using both mods together.
