OWR3 SG550 model on r_pop animation is my favorite SG550 model but I didn't like the look of M203 attached to the rifle so I replaced it with vanilla underbarrel grenade launcher as GL5040 was designed especially for this rifle. For the textures I used the one I found in Shoker Weapon Mod that makes old vanilla GL model to look good enough. Will work with OWR3 weapon pack. For use with any other pack could require adaptation.
