Ever wanted to get Counter-Strike source weapon models/skins in the old regular 1.6?
Well wonder no more because I have a guide to help you achieve that goal.

First, to start things off, I'm going to need you to download this file.
Once the download is completed, run the executable, and install it in a new folder, this way you can get the things you like, some people might not like the sound, or the player models, or the maps.
Right now, we're only looking for the model packs.

Open the folder that you installed your source models on, open cstrike, then models.
Now, scroll down to the bottom, and find the file that's labeled "v_ak47.mdl", once you have that file, you will need to find the last one, look for a file labeled "v_xm1014.mdl".

Once you have found those, highlight them, copy and paste them in your Counter-Strike 1.6's cstrike folder, NOT the folder that you installed the source model packs in. It should say something like a file with that name already exists, do you want to override?
If that occurs, simply press Yes.

It is recommended that you do a backup of your 1.6 weapon models as you might not like the source models, if that occurs, then you would have to either reinstall Counter-Strike 1.6 or find a way to get the old weapon models.

You can also do this for source maps or sounds, or the HUD, you just need to know where those are located.

Enjoy your new source models.
