In the Red Forest do the mission to get the compass which the forester sends you on and return to him. When you talk to him, tell him you have the artifact. He will then give you a fully upgraded Vintar VC. Do not continue the conversation. After he gives you the gun, exit the conversation then talk to him again. Tell him you have obtained the artifact again. He will give you another gun. This can be repeated as many times as desired and the guns can then be sold.
Getting to the Freedom Armory without being Part of FreedomAdded 9 Aug 2007, ID #11446
To get into the armory without being detected push a chair towards the guard. Don't worry if the chair falls down partway. When it touches the guard jump on it and then jump onto him. The game will then push you past the guard and into the armory hallway. To get in just slash the lock with your knife and to get out use the same technique you got in using a chair which is in the armory or the other room.
