Important things to know

This rifle can be abused and used to annoy and harass others. Don't do that. By purchasing and using it, you agree to use it with willing and consenting participants. No other application is intended nor endorsed.

Equipping the Rifle

You can attach the following components from your inventory by right clicking them and selecting 'Wear.' They will attach as follows:

  • 556 SWAT 1.0.3: (The important part) - Attaches to right Hand
  • 556 SWAT HUD 1.0: Attaches to screen bottom left (Mostly Optional - See 'Gestures and Chat Control')
  • 556 SWAT Slung 1.0: Attaches to right hip (Optional)

The Combat AO (Animation Overrider)

Built into the 556 SWAT is a complete animation overrider consisting of 41 custom-made animations geared toward combat usage of an assault rifle. Because of this, it is highly recommended that you turn off any other animation override or other devices which may animate your avatar. Each stance has its own set of animations, including transitions between stances, and all have holding, aiming and reloading animations.  Each also has animations unique to the stance, and in some cases, unique to the control inputs while in that stance:

  • Standing - Two walking animations, for movement while aiming (I.e. in mouselook) or while just holding the rifle.  Also running, but you cannot aim and run at the same time.
  • Kneeling - While in the kneeling stance, moving forward will result in a crouch-walk.  Running from a kneeling position will result in your avatar standing up and running, returning to kneeling or crouch-walking when running is stopped. The same applies to jumping from the kneeling stance.
  • Prone - Moving forward in prone will cause your avatar to crawl forward. Moving left or right will cause your avatar to crawl sideways, while keeping the body facing (relatively) forward.  Also, holding left or right (with shift if not in mouselook) will roll to the left or right side.  Running is not possible in prone, nor is jumping.


The HUD is made to provide you with an intuitive and fast interface that conveys the current state of the rifle at a glance.  Clicking the right hand side (where it says '556S' below) will cause the HUD to minimize itself, presenting an abbreviated interface.  Clicking the side of the minimized HUD will return it to full size.  These two modes can be independently positioned on your screen, and they will return to the previous screen position when that mode is again recalled.  To save yourself from tearing your hair out, if you reposition the HUD, do not immediately detach and reattach it or the HUD will seem to 'forget' where it was attached.  The HUD only remembers the position it was in when it is switched to the other mode, and SL prefers that you interact a bit with a HUD object before detachment before it will generally 'remember' the screen position of said object.


For toggle or state buttons such as draw, stance or weapon mode, a green button indicates the active selection.  Other buttons will hilight momentarily to provide visual feedback on activation.

  • Draw/Sling: Toggles the rifle between the drawn and slung positions.
  • Laser Designator: Selects Laser Target Designation mode.  A second press pops up the loadout selection menu.
  • Grenade Launcher Velocity: Raises or lowers the grenade launcher's velocity.  More filled circles mean higher, more empty circles mean lower.
  • Rifle: Selects rifle mode.  A second press pops up the rifle ammunition menu.
  • Ammo Level: Indicates the amount of ammunition available in the current magazine.
  • Fire Mode: Selects between semi automatic, burst and fully automatic rifle fire.
  • Rifle Velocity: Raises or lowers the bullet velocity.  More filled circles mean higher, more empty circles mean lower. In OCS mode, velocity is locked and can not be changed.
  • Grenade Launcher: Selects Grenade Launcher mode.  A second press pops up the grenade launcher ammunition menu.
  • Stance: Chooses between standing, kneeling and prone stances.
  • Option Menu: Pops up the Option Menu, which allows you to toggle the following features on and off:  Scope, Grenade Launcher, Stock (folded/extended), Shell ejection, Reloading, and Suppressor.
  • Colour Palette: Pops up the colour palette, from which you can choose your preferred colour of flare and smoke grenades.

Ammunition Types for Rifle, Grenade, and Laser Designator Modes

The 556 comes with a variety of ammunition types for its three modes.  (Do note:  In OCS mode, the selection of ammunition is limited to a pre-selected list of OCS-compatible ammunition. This would include OCS bullets and grenades, smoke, and flares.)

Ammunition with 'NP' designations are non-physical rounds and will report back when they find and engage a target.  This can get very spammy on full auto.  Non-physical ammunition is best used in semi-auto mode, or otherwise very short bursts, as being an axis-weighted seeking round, it's a guaranteed hit when it says it has targeted an avatar.

Rifle (i.e. Bullets)

OCS 556: The standard 5.56x45mm round for OCS combat.
OCS-TRC 556: A 5.56x45mm round for OCS combat with tracer effect.

DRIVE Ammunition: DRIVE ammo types affect either avatars or physical objects, and will 'drive' them away, pursuing the target across sim lines and persisting in its attack for 60 seconds.  Once started, DRIVE cannot be recalled or otherwise halted.  It will work in push or no-push zones, requiring only scripts to be enabled and objects to be rezzable.
DRIVE O NP 556: Non-physical, physics-enabled object seeking DRIVE round.
DRIVE NP 556: Non-physical, shield-passing avatar seeking DRIVE round.
DRIVE 556: A purely physical round, affecting avatars or physical objects upon contact.  Has a degree of shield-bypassing ability, as it will seek an avatar upon impact with a non-physical barrier such as a shield.

DMG 556: Your standard physical, Linden damage bullet. 100% damage on contact with an avatar.
DMG-TRC 556: Standard physical, Linden damage bullet with tracer effect. 100% damage on contact with an avatar.
DMG NP 556: A non-physical, shield-passing version of the  Linden damage bullet, dealing 100% Linden damage.


40mm M433 OCS: High explosive, dual purpose round for use against light vehicles and personnel. Delivers both OCS and Linden damage
40mm M583A1: Harmless flare round used for illumination. Do note: This is NOT the 'popup' style of flare, this flare should be fired directly into the air. It will ignite and drift with the wind about 1 second after launch, so higher grenade velocities will result in ignition at higher altitudes and/or further ranges.
40mm M717: Smoke grenade which deploys upon impact.
Rangefinder:  The Rangefinder selection enables use of the grenade launcher's automatic ranging and ballistics mode.  To use, select 'Rangefinder' from the grenade ammo menu. Aim where you wish to deliver a grenade and fire. After a short pause, the launcher calculates a firing solution taking into account target position, target velocity and wind and fires a M433 OCS round.

Laser Designator

LD OCS: In OCS, this is the most basic of the three laser designator loadouts.  Aimed at a target, it allows guided OCS weaponry to home in on its location, enabling precision strikes against pesky hard-to-hit targets.

The two other loadouts need a little explanation.  After you select your target and designate it, an X-47B Unmanned Combat Air Vehicle will fly in overhead and release a GBU-10 laser-guided bomb onto your target or, in the case of the LD B83 loadout, a B83 thermonuclear gravity bomb.  Yes, really.  The one caveat to this is that the X-47 will fly in from the corner of the sim that's furthest from the designated target, and requires a clear path (i.e. nothing in the air to fly into), and no parcels which do not allow object entry or that do not allow rezzing of objects and running of scripts.

The aircraft can be shot down before it reaches its drop point by large-caliber anti-aircraft fire or attentive FIM-92 Stinger operators.

LD OCS (CAS):  Uses the X-47B to deliver a GBU-10 2000 pound bomb accurately on target.
LD B83: High yield Linden-damage enabled thermonuclear device with a very large fireball and range of effect.

Gestures and Chat Control

The 556 SWAT can be used for most functions without the HUD.  The channel for chat control is channel 5, for which you can thank Eata Kitty of Breach.   This means commands can be given in the form of "/5 command" such as "/5 draw" (without the quotes, of course).  Commands which are accepted on channel 5 are:

draw: Toggles drawing or slinging of the rifle.
stand: Sets the stance to standing.
kneel: Sets the stance to kneeling.
prone: Sets the stance to prone (lying).
gl: Grenade launcher mode.
semi: Semiautomatic rifle mode.
burst: Three-round burst rifle mode.
auto: Full automatic rifle mode.
lase: Laser designator mode.
shells off: Disables ejection of spent casings and empty magazines.
shells on: Re-enables ejection of spent casings and empty magazines.
reload off: Disables reloading of magazines for uninterrupted fire.
reload on: Re-enables reloading of magazines for uninterrupted fire.
ammo: Pops up the rifle ammo selection menu.
glammo: Pops up the grenade launcher ammo selection menu.
laseammo: Pops up the laser designator loadout selection menu.

gl on: Equips the grenade launcher to the rifle.
stock fld: Folds the stock.
stock ext: Extends the stock.

Included in the kit are several gestures you can activate and use for oft-used functions such as drawing/slinging, stances and reloading.  Do note that you may have other gestures using the same F-keys as the ones included in this package. To locate and correct these conflicts, press control - G in your viewer and click on the"Key" column header to sort by key assignment. The F-keys are merely my suggested key bindings, feel free to reassign them to whatever works best for you.


Q: Will the 556 SWAT work with my Roleplay Combat System?

A: They may. To date, we have not heard of any systems that the 556 SWAT will not work with. However, The Omega Concern does not guarantee compatibility with any other system but OCS and the Second Life Damage model.

Q: What is OCS?

A: OCS stands for Omega Combat System. It is the official combat system of The Omega Concern and Fulda Gap. It represents thousands of hours of testing and design to bring you the most lethal and realistic combat model seen in Second Life to date.

Q: Why do I seem to miss with my 556 SWAT in OCS?

A: OCS uses a realistic accuracy scale. Practice makes perfect, and as you progress in skill within the OCS system, you will become more and more accurate with your weapons. Remember: OCS levels are life long levels.

The End

In short, this rifle is meant to deliver devastating fun, and work as a strong statement of your excellent taste for wielding a quality Omega Concern product. The Omega Concern promises to support your 556 for the lifetime of the product, with free updates and bug fixes for all of version 1.x.

Above all else, have fun. :)
