There is evidence of an SDAR with a Rail, it can easily be found, and with only a Config, could be brought to life. At one point long ago, i'd requested a railed version of the SDAR, why not?
Here is it's config already in existence...
Here's the contents of the SDAR config...
-----------------------------------------
class WeaponSlotsInfo: WeaponSlotsInfo
{ class MuzzleSlot{}; class CowsSlot{}; class PointerSlot{}; };
And for the TRG series' Tavor_base_F:
class WeaponSlotsInfo: WeaponSlotsInfo
{ class MuzzleSlot: MuzzleSlot { linkProxy = "\A3\data_f\proxies\weapon_slots\MUZZLE"; compatibleItems[] = {"muzzle_snds_M"}; iconPosition[] = {0.0,0.4}; iconScale = 0.2; }; class CowsSlot: CowsSlot { iconPosition[] = {0.45,0.28}; iconScale = 0.2; }; class PointerSlot: PointerSlot { iconPosition[] = {0.25,0.4}; iconScale = 0.25; }; };
