The Anvil blueprint was found in a handy hideout hole on Dam Battlegrounds, which always seems to spawn raider containers. The buy arc raiders blueprints can be found in a tiny void where the raised highway ends at Dam Battlegrounds. The locati0n is located between Raider Outpost East and East Broken Bridge.

 As you can see, this is an uneasy spot. The safest way up is to take a zipline off the ground. However, if you prefer it is possible to drop from the highway and hold the arc raiders shop vault (Spacebar on your keyboard) to catch the ledge as you fall. The timing is good so don't stress about it. If you do fall and hurt yourself, it's not fatal (but it will cause injury).

 I rushed to the highway entrance and came across a backpack belonging to a raider with a box containing:

 Anvil blueprint

 Bettina blueprint

 Ammo

 Health stim

 Herbal bandages

 Shield charger

 Durable cloth

 Bandages

 It is also possible for a weapon box to spawn, which will contain a gun as well as blueprints.

 This is one of the easiest and most reliable ways to find blueprints in Arc Raiders. There are Raider caches across all maps, but they are usually found in high-loot areas where Arc patrol. This dusty stretch of highway is a quiet, arc-free area and close to spawn points for Dam Battlegrounds. If you're lucky, it'll be an easy 30-second sprint.

 Alternatively, you could venture into the Buried City map, and then head towards senior guides' Sean Martin's preferred place to find treasure: Marano Station. Marano Station, like the highway in Dam the Dam, is a peaceful region on the edge which contains a few caches. Sean found a blueprint for Anvil in addition to other blueprints.

 Only catch, the loot's hidden behind a locked door you have to open. It makes more noise than players hear on the smaller map. Since the area is more apparent, other players are more likely to be there ahead of you.

 Once you've learned the Anvil blueprint, you'll need an advanced Gunsmith bench in order to build it. From there, it's very expensive to make: 5 Mechanical components and 6 gun parts.Here is the Anvil blueprint I found in Arc Raiders

 The intricate revolver blueprint is easiest to find inside raider containers. These are readily available if you know where to search.

 Looking for the missing Arc Raiders Anvil blueprint? Blueprints are among the rarest drops in Arc Raiders, as they unlock the ability to craft weapons indefinitely instead of waiting for them to become available in the shops.

 The Anvil is a fantastic blueprint to secure early on thanks to the gun's high damage and its Arc armor-penetrating heavy ammunition. It's like carrying a Ferro which you don't need to reload every time you shoot.

 Because blueprint spawns can be random, there's no guaranteed location to obtain the Anvil blueprint. There are raider containers that have the potential to contain weapon blueprints. Due to the investigation efforts of the community they can be tracked down with consistency.
