  FIREARMS DESIGN
  "I believe everyody in the world should have guns. Citizens should have bazookas and
  rocket launchers too. I believe that all citizens should have their weapons of choice.
  However, I also believe that only I should have the ammunition. Because frankly, I
  wouldn't trust the rest of the goobers with anything more dangerous than string."
  -Scott Adams
  These rules are intended to allow players and
  gamemasters to design and customize weapons
  based on the Shadowrun, Third Edition standards.
  The design sequence is intended to produce
  weapons that are as realistic as possible and yet still
  be directly compatible with previously published
  weapons.
  Unless otherwise noted, these rules are intended to
  produce modern firearms. That is, weapons that use
  a fixed cartridge consisting of a bullet (or bullets),
  propellant, and primer.
  THE DESIGN PROCESS
  The design process begins with selecting a frame
  for the weapon, which gives the range of
  compatible round caliber's and its starting Design
  Point cost. The designer then chooses what sort of
  firing mechanism the weapon will use and the
  actual caliber of round that it will fire. The designer
  then picks a barrel length and additional options.
  The design sequence is as follows:
  1. 
  Choose a Frame
  2. 
  Choose a Firing Mechanism
  3. 
  Select Barrel Length
  4. 
  Choose a Caliber
  5. 
  Add Additional Options
  6. 
  Calculate Derived Statistics
  1. SELECT A FRAME
  The weapons frame is arguably the most important
  aspect of the weapons design. The weapons frame
  not only determines the weapons base cost, but also
  available mounting locations for additional options
  and what calibers the weapon supports. It also
  determines what skill is used when firing the
  weapon.
       Mechanisms: This will list the available types
  of firing mechanisms for that frame.
       Mounts: The available locations to mount
  additional options on the weapon.
       Calibers: The round calibers that the frame can
  be designed to fire
       Barrel: The minimum and maximum length of
  the barrel that can be used with the frame.
       Size: The frames base number of Size Points
  (SP).
       Weight: The frames base number of Weight
  Points (WP).
       DP: The number of Design Points (DP) that the
  frame costs.
  2. CHOOSE A FIRING MECHANISM
  The firing mechanism will determine what firing
  modes the weapon can utilize.
       Mode: The firing mode that the weapon
  possesses with this option.
       DM: The modifier to the weapons final Power
  or Damage Level (if any).
       Size: The mechanisms base number of Size
  Points (SP).
       Weight: The mechanisms base number of
  Weight Points (WP).
       DP: The number of Design Points (DP) that the
  mechanism costs.
  3. SELECT BARREL LENGTH
  From the range of barrel lengths given for the frame
  type the designer should choose a barrel length. If
  converting a real-word weapon to this system then
  only use the length for the barrel itself, without
  factoring in the receiver assembly.
  The weapons barrel length will impact the weapons
  final size as well as the adjusted damage for the
  weapons projectiles (see below).
  4. CHOOSE A CALIBER
  This is the actual round that the weapon will be
  firing. Consult the Caliber Compatibility Chart to
  check that the chosen frame can fire the round.
       Base Damage: The base Power and Damage
  Level for the round unadjusted for barrel length or
  frame.
       Barrel Length: These list the breakpoints in
  barrel length, and the adjusted damage of the round
  fired from it. If the weapons barrel length does not
  match any of the listed lengths then round to the
  nearest listed length.
       Barrel Points: The Barrel Points are added to
  the calibers base SP, WP, and DP.
       Range: The weapons range band.
       Size: The mechanisms base number of Size
  Points (SP).
       Weight: The mechanisms base number of
  Weight Points (WP).
       DP: The number of Design Points (DP) that the
  mechanism costs.
  
  5. ADD ADDITIONAL OPTIONS
  These are additional modifications and additions
  that can be added to the weapon at design time.
  Unless otherwise noted these options may not be
  added at a later time.
  Most options have their prices listed either as
  positive or negative percentages. All of the weapon
  options modifiers are added together before final
  calculations.
  For example, a weapon that has two options with
  +5% DP and a single -5% option will total +5%
  when calculating the weapons final DP total.
       Price Factor: The options Price Factor (if any).
       Size: The multiplier to the base number of Size
  Points (SP).
       Weight: The multiplier to the base number of
  Weight Points (WP).
       DP: The multiplier to the base number of
  Design Points (DP).
  6. CALCULATE DERIVED STATISTICS
  This is the final stage of weapon design. There are
  X derived statistics, and they are listed below:
       Weight: This equals the total number of Weight
  points multiplied by the total Weight multiplier for
  the various options. You then multiply that total by
  the weapons original number of Weight Points.
  This total is then divided by 200 to give the
  weapons final weight in kilograms. Round to the
  nearest 10th of a kilogram.
      Concealability: This is determined by
  multiplying the total number of Size Points by any
  Size Multipliers for option. The number is then
  divided by ten, rounded down. This result is then
  subtracted from 10 to give the weapons base
  Concealability.
       Cost: The weapons cost in nuyen is equal to its
  total number of Design Points multiplied by 10.
  The final number then multiplied by its Price Factor
  to get the final cost. Round to the nearest 100
  nuyen.

  OPTIONS
  Unavailable Mounting Space
  One space from the frame is disabled, which limits the ability to add some options.
       Price Factor: -5% per unavailable space
       Size: None
       Weight: None
       DP: None
  Steel Construction
  Steel is used for the weapon, instead of alloys. This is cheaper but also heavier than standard alloy. No firearm
  may have more then 2 levels of steel construction. Steel construction is not compatible with polymer-resin or
  ceramic construction.
       Price Factor: -5% per level
       Size: None
       Weight: +10% per level
       DP: None
  Polymer-Resin Construction
  The weapon may have no more then two levels of polymer construction. It may be combined with ceramic
  construction, but in that case each modification is limited to one level.
       Price Factor: +15% per level
       Size: -10% per level
       Weight: -10% per level
       DP: None
  Ceramic Construction
  The weapon may have no more then two levels of cermic construction. It may be combined with polymer-resin
  construction, but in that case each modification is limited to one level.
       Price Factor: +30% per level
       Size: -15% per level
       Weight: -20% per level
       DP: None
  Bullpup Design
       Price Factor: +30%
       Size: -20%
       Weight: None
       DP: None
  Folding Stock
  This is only available to frames with the Stock mounting space. It removes the solid stuck with a folding version.
  The size reduction only applies when the stock is folded. While the stock is folded the weapon has double the
  usual recoil penalties. It requires a Simple Action to unfold a stock.
       Price Factor: None
       Size: Final Size Points are reduced by 40% when calculating Concealability while folded.
       Weight: None
       DP: 5
  Personalization
  This option allows for the end-user to adjust the grip to a more comfortable setting, thereby giving 1 point of
  recoil reduction.
       Price Factor: None
       Size: None
       Weight: None
       DP: 15
  
  Gas Vent
  Max Level 3. Each level grants 1 point of recoil compensation. Uses the Barrel space. When calculating
  damages, each level shifts the effective barrel length down by one category.
  For example, a 9mm with a barrel length of 12cm and two levels of Gas vent will use the 7cm barrel length
  for calculating damage and range (but not Barrel Points).
       Price Factor: None
       Size: None
       Weight: None
       DP: 15 per level
  Improved Gas Vent
  Max Rating 4. Grants (Level+1) points recoil compensation. Uses the Barrel space. When calculating damages,
  every two full levels of Improved Gas Vent shifts the effective barrel length by one category.
       Price Factor: None
       Size: None
       Weight: None
       DP: 25 per level
  Shock Pads
  Max Level 2. Uses the Stock space. Grants as many points of recoil compensation as the level. May not be
  combined with a folding stock
       Price Factor: None
       Size: None
       Weight: 2 per level
       DP: 5 per level
  Smartlink Level I (Internal)
  Uses either the Grip or Under space.
       Price Factor: None
       Size: None
       Weight: None

  Smart Safety
  Can only be used with an integral smartlinked weapon. A small firmware chip is encoded and encrypted with the
  Serial Number of the corresponding connected device (smartlink interface, datajack or smartgoggles). Upon any
  attempt to fire the weapon, it interrogates the connected device and will remain on safety until connected to an
  authorized device.
  Removing the smart safety requires a Gunsmithing (4) Test, with a Base Time of 2 hours.
