    WHAT MODS ARE:
    Weapon mods can be found at various vendors throughout the Wasteland, but the best place to go is "Gun Runners" near the New Vegas Strip. They usually have a lot of gun mods in their inventory under "Misc". You will need to have the gun you buy the mod for in order to install it. Note: Every vendors' inventory recycles over time, so there are more than enough opportunities to collect weapon mods. If, however, you want to get this done as fast as possible, there is a way to "force" a vendor to change to new mods. See the bottom of this solution for directions.

    Here is the location of Gun Runners (JPEG):

    HOW TO INSTALL:
    To install a mod, go to the Weapons section of your Pip Boy and scroll to the weapon you bought the mod for. Click the LB (Left Bumper) and a list will open up of available mods for that weapon. Just click A on the mod you want and the next time you take out your gun you will notice your shiny, new addition. These mods do not need to each be unique for the achievement. You can use duplicates of the same mods or on the same weapon.

    HOW TO FORCE NEW MODS:
    Vendors' inventory changes every 72 hours or so, so press the Back button and wait for ~3 days and then check with the vendor again for new mods. You can also try the following:

    Ashen SeraphThe GRA DLC makes this a whole lot easier. There are far more weapons with mods added to the game when using this DLC, some of which are far more readily available and far cheaper than those in the base game.

    As some of the people above have mentioned, Gun Runners is the best spot, in my opinion, to get this done in a matter of minutes.

    Instead of spending tons of caps and maybe not getting the achievement to pop, just go to Gun Runners and buy the Varmint Rifle then purchase the Varmint Rifle Silencer. It's a total of 261 caps so just mod that then wait 3 24-hour periods. Rinse and repeat until the achievement pops.

    IxI KILLING@A S0T I am not positive on the patch but I don't see why the would have. I can't confirm this but maybe someone else can, I hope.

    You can buy/find mods everywhere and if you got two 9MM pistols, you can buy two scopes and place them on each weapon. This counts for 2 mods.
    In total you can place 3 different mods on 1 weapon (ex. Varmit Rifle with Night Scope, Silencer and Extended Mags).

    Locations for mods:

    Great Khan Armorer, entrance of the Red Rock Canyon, sells mods for Guns.
    Blake, Crimson Caravan Company (north of Freeside), sells mods for Energy W. and Guns.
    Vendortron, Gun Runners, sells mods for Energy W., Explosives ad Guns.
    Gloria Van Graff, Silver Rush in Freeside, sells mods for Energy W.
    Dale Barton, The Fort of the Legion, sells mods for Energy W. and Guns.
    Chet, Goodsprings, sells mods for Guns.
    Michelle, 188 Trading Post (on your way from Boulder City to Vegas), sells mods for Guns.
    Knight Torre, Hidden Valley (Brotherhood of Steel), sells mods for Explosives and Guns.
    Old Lady Gibson, Gibson Scrap Yard (north of Novac), sells mods for Energy W.
    Cliff Briscoe, Novac Dino Shop, sells mods for Energy W. and Guns.

    Dokter VLater on in the game (after you went to Vegas and did some main quests for either NCR, House, Legion or Yes Man), he sells some 9MM scopes and drums for the 9MM SMG. Personally I bought a Night Scope and Extended Mags for the Varmit Rifle.
