I don't know why the reload anims are like that,so I will leave them how they are.Also unlike in the video the weapon has official MW3 sprint anims.I've used MW3 Model 1887 anims,custom ADS anims and BF4 870 MCS/Mare's Leg sounds.
I couldn't do this port alone,so I want to thank multiple people for making this port possible:
-Hitman Vere: Fixing the Normal map for me
-DamianoTBM: Model 1887 assets and some help
-Rorke: Some other Model 1887 assets
-BeamSP/BeamedTheSpeed: Weapon file
-Tom_BMX: Lime/Lemon
-Scobalula: Maya shelf for anims
-Call of Duty Wiki+Marvel4: Stats
-Infinity Ward: Anims
-Dice: Sounds
-Ubisoft Entertaiment: Original Model
-Pack 3D Models User Admin: Providing the model
I hope you enjoy this port!
