A classic PSO-1 mod for the FY71, commonly used on an SVD sniper rifle. This may work with Warhead, but I'm not sure.
Copy and past the *.pak file into your Crysis/Game folder.
I've set the PSO-1 to automatically attach itself when given the weapon.
There are 2 different version of it, rubberless and standard.
This is setup for the FY71 only, and I don't give a flying fuck if you add it to other weapons. Open source is what I do.
I do like to keep track of my overall download count, so redistributing
