Nailed It!
Get 100 kills with the Nail Gun

Maps that have nail gun:

Backwoods: easiest map to obtain the Nail Gun. When the match starts, simply turn around and run towards the back of the map. If you go far enough, you'll see the weapon spawn near a small trailer or in a large wood cabin in what appears to be a lumber yard.

Black Friday: Spawns the weapon near the escalators on either side of the map. Keep an eye out, as one side is on the second floor and the other is on the ground level beside the escalator. This one is also near the spawn point on Blood Money, though you'll have less luck obtaining it as it's in the direction most players will be heading.

Code Blue: Has one spawn that is easy to identify an done that is kind of weird. The first is near the construction area. There's a series of "stairs" in the back of the building, which you use to get to the top. The two buildings connect by a thin beam, so be careful not to fall if you climb up the wrong building. The other spawn is towards the "city" area on the other side of the map. In a small, fenced off area beside a ladder you'll see the Nail Gun.

The Beat: The Nail Gun spawns in a two floor building relatively close to the spawn. People often scoop them up on the way to the middle, hence why you don't see them very often.

Locked & Loaded, Good to Go
Enter a match after crafting weapons in all five Gun Bench slots

You have to be level 50 ingame before you even attempt to start getting kills that count towards this achievement.
So in the newest Betrayal DLC, a new feature has been added to Hardline called the Gun Bench. The Gun Bench can be accessed by clicking on the "Multiplayer" tab. It should be among the multiplayer options. In the Gun Bench you start out only being able to customize 3 weapons, but the max you can customize after unlocking the other slots is 5.

To get this achievement you must unlock the other 2 Gun Bench slots. The 4th slot is unlocked by completing an assignment that requires you to customize 1 weapon in the Gun Bench (although you can customize up to three at this point) and then get 100 kills with those Gun Bench guns. The 5th slot is unlocked by having the previously mentioned assignment completed, customizing 4 guns in the Gun Bench, customizing 4 outfits (which is also done in the Gun Bench) and getting 1,000 kills with Gun Bench guns. Once you have customized a weapon in the Gun Bench, make sure you press start and save and quit.

In order to equip the Gun Bench gun that you customized, enter a match and go to whatever class the weapon is for and there will be a new option at the top of the gun selection screen that says "Custom 1", "Custom 2" etc. Choose any of your custom weapons and next time you spawn you will have the Gun Bench gun equipped. You can't edit the weapon ingame, only in the Gun Bench.
