It's a very nice gun, but its barrel component is missing and the connection is incorrect, and it lacks some textures. So in the dark environment of the building, the gun body will appear black and the body will be transparent and other problems.

I have fixed them all without making too many changes. I will give you the best effect.

Thank you for downloading. Wish you a happy time: )
