Weapons can be upgraded with attachments such as Scopes & Silencers that are found in the game or purchased from vendors, and whereas weapon damage/clip ammo/accuracy can be upgraded using crafting parts. Hold while highlighting a weapon in your inventory to bring up the upgrade screen, max out any specs available for upgrade and equip the attachments that are applicable to unlock this. An easy one is the Tranquilizer Rifle which only needs the Laser Targeting System and clip ammo upgrades.
The fastest way to earn this achievement is by fully upgrading the Stun Gun. You have the opportunity to receive it during the start of Mission 1, or you can hack into the weapons locker at TF29 to get one. There is no penalty for hacking into the weapons locker...you work there after all.
It'll take around 550 crafting materials to upgrade the ammo capacity, and you will need a laser sight attachment as well. This attachment can be bought from the weapons vendor in Jensen's apartment complex or found through open world exploration.
Once you have the necessary materials, open your inventory and tap twice while hovering over the Stun Gun to customize it. Attach the laser sight, upgrade the ammo capacity three times, and the achievement will unlock.
