All install info in the readme.

This mod includes dual-wield for all the handguns, and mp5.
faster fire rate for all guns more accuracy for some guns and more range for all of the guns(except for the spas-12 which already had too much). when using the unscoped rifle or the country rifle you have more zoom when holding down the right-click button.

Download the semiautomatic file if you want your country rifle and sniper rifle to be semiautomatic as well as all the other changes. The country rifle has a 15 clip size and the sniper rifle has a 5 clip size.

Download the pro versions if you want this even more realistic. They have much less accuracy and you actually have to reach hitman level to dualwield weapons.

Known issues:
when shooting with the country rifle the gun does not stay aimed but only aims when you shoot, producing a quickscope effect. This does not change anything but how it looks.I could probably fix this but won't because it looks cool.

Other bugs and issues: if you find any bugs or issues with this mod tell me about them in the comments.
