How to unlock the Lock, Stock, And Then Some achievement in Call of Duty: Black Ops III - Definitive Guide
This can be unlocked using any weapon, but I'd personally suggest using the XR-2 burst-fire assault rifle for this.
Not only will you rack up a significant amount of kills with it in the second mission of the game, but you'll already have unlocked more than half of the attachments for it by the time you reach the Safehouse.
There's also the fact that it's a three-round death machine if you combine the FMJ and High Caliber attachments.
Simply use this as your main weapon for missions 3 and 4, "In Darkness" and "Provocation", and this achievement should pop up sometime during the fifth mission, "Hypocenter".

Just use one weapon for the whole campaign, and you will eventually reach max level with it, thus unlocking all attachments.
Every primary weapon and secondary pistol (except Annihilator pistol) has attachments, and these are unlocks by levelling your gun. In order to level your weapons, you simply need to get kills with them. It should only take a few hundred kills with a weapon to reach max level. Pistols have fewer attachments and therefore will hit max level faster.

Definitely get it, just run through 2-3 missions to unlock all the modules on one barrel.
