---------------------------------------------------------------------------------------- “What is a Breacher?” ---------------------------------------------------------------------------------------- The Breacher is a 3d printed DIY Nerf-style foam dart blaster, which uses a 3d printable shell (Silly Shells) to hold several darts at once, to fire multiple darts each time you pull the trigger. Breacher is modeled after pump action shotguns, with a tube magazine that holds 4 to 6 shells (depending on which muzzle tips you have installed). Breacher is able to fire many different types of foam projectile, including Nerf Elite darts, Nerf N1 darts, half darts, Rival balls, Mega, MegaXL, and more. That all adds up to make Breacher a very fun, and very satisfying shotgun-style blaster!

There are many, many different shells to use in each blaster, allowing one blaster to fire a wide variety of ammo types without reconfiguration or modding. For example, you can fire 3 Elite darts out of one shell, eject it, and then load a MegaXL shell to fire a huge dart at your enemies! Then you can follow that up with a “buckshot” round of Rival balls. Then you can load a Bottlenose shell to hit a person across the field from you. Silly Shells allow you to use multiple different types of foam ammo in one blaster, and they allow you to fire multiple darts with just one shot of the blaster!

Please refer to the file listing for Silly Shells to download them all and get more information.

Please check the shell compatibility spreadsheet to see which Silly Shells work in this blaster.

Note: Breacher's magazine and feed system does not fit any shells that have ammo sticking out past the tip (full length Mega or MegaXL), however, you CAN still breech load them one at a time into the blaster for single shots.

---------------------------------------------------------------------------------------- Performance ---------------------------------------------------------------------------------------- Breacher should have the same FPS performance as Battle Axe: https://docs.google.com/spreadsheets/d/1Pixa7pvZfWJ54Cy2VnBE_0UdA56MWYw5ja8P_bJ5XCY/

---------------------------------------------------------------------------------------- Part Options ---------------------------------------------------------------------------------------- Breacher can be customized by mixing and matching the available alternate files: - 4 different priming handle options - Default, Slim, SlimGrippy, and Picatinny.

- 2 sizes of magazine capacity extension tubes, which as super easy to swap!

- Alternate files with various sling attachment points on them

- Alternate files for printing the longest parts (the priming bars) on a 180x180mm build plate printer. Everything else will fit already!

- 2 types of magazine follower, for compatibility with several types of drum spring hardware.

Also, there are STEP and F3D source files available for you to customize the blaster even further yourself!

---------------------------------------------------------------------------------------- Print Info ---------------------------------------------------------------------------------------- The correct 3d print files for the follower and follower rollers are determined by which spring you have. If you have FoamBlast Style drum springs, use the FBdrumSprings files. If you have generic drum springs, use the GenericDrumSprings files.

NOTE: If your hardware kit is using a k25 5.5" long spring, you will need the optional spacer print for the PTguide to prevent the spring from rattling (if spring rattle annoys you)!

Filament usage and print time estimates (PLA filament) (Includes supports and brims for recommended parts): - All parts together: 1962 grams of filament

- Green: 1003 grams (be very careful with the green folder prints, or make sure to have 2 spools of the filament on hand in case one runs out!)
