Thank you and congratulations on your purchase of The Omega Concern's Mk17 SCAR-H EGLM assault rifle. Please read this manual before using your new assault rifle.

The Omega Concern is dedicated to producing quality work at affordable prices, and we support everything we sell. All of our products are designed with the balance of impact on sim performance and ease of use in mind. If you find one of our products to be causing lag, behaving in unexpected ways, or otherwise being a pest, we need to know so we can correct it.

You are eligible for all upgrades on this version, being version 1. Also, your feedback is valued! If there's something you love, hate, or just think would be better if it were just a little different, we want to know. Your input directly influences the course of development and future features of Omega Concern products.

There is a technical support pass phrase in this manual, which you are strongly advised to use when first contacting support about this product. We do this because other people (not you!) don't bother reading the manual which contains the answers to their questions, thus taking our time and attention away from thoughtful questions not answered in the manual, such as yours. As always, emailing the support address above is preferable to offline IMs and notecards, both of which too easily get lost in the shuffle.


About the Mk17 SCAR-H EGLM

The Omega Concern's Mk17 SCAR-H EGLM is a selectable fire 7.62mm assault rifle equipped with an Enhanced Grenade Launcher Module (EGLM) with optional auto-ranging, and a laser target designator with dedicated, on-demand support in the form of a MQ-8B Fire Scout semi-autonomous helicopter UAV.

The Omega Concern is not affiliated with, nor endorsed by FN Herstal, BAE Systems, Northrop-Grumman, or any other company involved in the design, production or manufacture of the Mk17 SCAR-H EGLM and MQ-8B Fire Scout. All trademarks and copyrights are and remain the property of their respective owners.

  1. Unpacking and Equipping

    1. Package Contents

      The Mk17 comes in a very handsome box. Try to avoid being dazzled by its rugged good looks. You will need to rez this box, and select "Open". You shall be presented with a window that looks much like this one:

      Press the button "Copy To Inventory", and you will now have a new folder in your inventory named "Mk17 SCAR-H EGLM 1.0 (Boxed)" (or similar) which will contain the above items from this charming and attractive box.

    2. Attaching Components

      The Mk17 is a mesh model, which means you will need a viewer capable of displaying mesh. The standard SL viewer is one such option, as are several others on the Third Party Viewer Directory.

      Mk17 SCAR-H EGLM 1.0: The most important part of the whole package. This is the actual rifle and it must be attached to your avatar's right hand (its default) for it work.

      Aside from the rifle itself, the Mk17 comes with several accessory attachments, all of which are optional:

      Mk17 HUD 1.0: The Heads-Up Display for the rifle, and the easiest way to operate it, which is explained in the next section. Its default attachment point is screen lower left.

      Mk17 Reticle 1.0: A reticle that shows in mouselook, giving you immediate feedback on what mode your rifle is in, and in the case of manual grenade launcher operation, range markers. Its operation is also described in the next section. Its default attachment point is screen center.

      Mk17 SCAR-H Slung 1.0: A model of the Mk17 with the stock folded. Its default attachment point is Chest.

  2. The HUD and Reticle

    1. Mk17 HUD

      1. Ammo Level: Indicates the amount of ammunition available in the current magazine. The Mk17 magazine has a capacity of 20 rounds.

      2. Stance: Chooses between standing, kneeling and prone stances.

      3. Rifle: Selects rifle mode. A second press pops up the rifle ammunition menu.

      4. EGLM (Enhanced Grenade Launcher Module): Selects Grenade Launcher mode. A second press pops up the grenade launcher menu:

        1. M433 HE, M717 Smoke, M583A1 Flare, and XM1055 Incendiary grenades may be selected here. They are described below.

        2. AutoRange: Selects automatic or manual ranging for the grenade launcher.

        3. Smoke/Flare Color: Pops out the color palette, from which you may customize your smoke and flare color.

      5. Laser Designator: Selects Laser Target Designation mode. A second press pops up the lasing and MQ-8B Fire Scout menu, which is described below.

      6. Velocity: Raises or lowers the velocity of projectiles fired in the current mode. More filled circles mean higher, more empty circles mean lower. In OCS mode, velocity is locked and can not be changed.

      7. Draw/Sling: Toggles the rifle between the drawn and slung positions.

      8. Options: Pops up the options menu, which presents the following:

        1. HUD Opacity: Allows you to alter the opacity (transparency) of the Mk17 HUD.

        2. Ret. Color: Pops out the color palette for setting the Mk17 Reticle color.

        3. Ret. Opacity: Will cause the Mk17 Reticle to come into view while out of mouselook so you may adjust the opacity (transparency) of the Mk17 Reticle.

        4. Shells Off/On: Enables or disables ejection of spent casings and empty magazines.

        5. Reload Off/On: Enables or disables reloading of magazines for uninterrupted fire. (In OCS mode, this can not be disabled.)

      9. Fire Mode: The Mk17 has only two modes of fire, semi-automatic and fully automatic.

      10. Minimize/Maximize: To minimize or maximize the Mk17 HUD, click and hold on the cog icon (Options) until the button turns from orange back to white, which takes about half a second.

    2. Mk17 Reticle

      The Mk17 Reticle will appear when you go into mouselook, and will automatically change with your rifle modes to give you immediate feedback on what mode your rifle is in (i.e. rifle, EGLM or lasing), and in the case of manual grenade launcher operation, provides range markers for more accurate placement of grenades.

  3. The Combat Animation Overrider

    Built into the Mk17 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:

    1. 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.

    2. 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.

    3. 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.

  4. ShortRound™

    The Mk17 is enhanced by The Omega Concern's ShortRound™ technology. ShortRound was developed to deal with the age-old physics simulation issue of trying to shoot something that's very close and having your bullets pass through your target without effect. ShortRound means you can fire at - and hit - targets that are less than one meter away, giving you a tremendous advantage in close quarters combat. Your support phrase in fact is "Short Round."

  5. Ammunition Types and Operation

    The Mk17 has a variety of ammunition types for its three modes. (In OCS mode, the selection of ammunition is limited to a pre-selected list of OCS-compatible ammunition.)

    1. Rifle

      1. OCS 762: The standard 7.62 x 51mm round for OCS combat.
      2. OCS-TRC 762: A 7.62 x 51mm round for OCS combat with tracer effect.
      3. DMG 762: Your standard physical, Linden damage bullet. 100% damage on contact with an avatar.
      4. DMG-TRC 762: Standard physical, Linden damage bullet with tracer effect. 100% damage on contact with an avatar.
      5. DMG NP 762: A non-physical, shield-passing version of the Linden damage bullet, dealing 100% Linden damage.

        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 762: Non-physical, physics-enabled object seeking DRIVE round.
        DRIVE NP 762: Non-physical, shield-passing, avatar seeking DRIVE round.
        DRIVE 762: 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.

    2. Grenades

      1. M433 HE: High explosive, dual purpose round for use against light vehicles and personnel. Delivers both OCS and Linden damage.
      2. XM1055 Incendiary: Burns intensely for 20 seconds, and will ignite OCS structures. And players.
      3. M717 Smoke: Smoke grenade which deploys upon impact, color selectable via the grenade menu.
      4. M583A1 Flare: Harmless flare round used for illumination, color selectable via the grenade menu. These should be fired upward to deploy above the area to be illuminated.

        When using autorange mode, simply aim where you wish the grenade to land. When in manual ranging mode, elevate the rifle until the intended target is centered at the appropriate range mark on the EGLM reticle. Autoranging will not work over region borders. If you attempt to range to an invalid target (in another sim, empty sky, etc) the launcher will default to ranging at 64 meters.

    3. Laser Designator

      1. Lase OCS: "Paints" a target for guided munitions to home in on, such as the CRV-7 and APKWS rockets on The Omega Concern's WAH-64 and AH-64D Apache.
      2. Deploy MQ-8B: MQ-8B Fire Scout operation is described in full below.

  6. MQ-8B Fire Scout Operation

    The Mk17 is complemented by the ability to call in and direct the MQ-8B Fire Scout, an armed, unmanned, semi-autonomous helicopter UAV for target engagement using guided APKWS (Advanced Precision Kill Weapon System) rockets. This UAV will establish a holding pattern above your position while waiting for you to designate targets for it, and will depart and exit the theatre after it has expended all its munitions, you have cancelled its support, or it is destroyed. In OCS mode, you will have to wait five (5) minutes to call another MQ-8B for support.

    1. Deploying

      Select the "Deploy MQ-8B" option from the laser designator menu. The UAV will require 10-30 seconds to arrive in the theater, and it will approach from the edge of the region directly behind you when you call it. Keep this in mind so as not to inadvertently cause the MQ-8B to overfly hostile positions which you do not have line-of-sight on, as it will not engage targets that you do not designate for it.

    2. Designating Targets

      To designate a target for the UAV to strike, while in lasing mode, point the rifle at the intended target and pull the trigger. Target designation will not work over region borders. The MQ-8B will acknowledge the target has been added to its target queue. If you make an error, bring up the laser designator menu and select "Clear Queue" and all targets will be removed from its target queue.

      The MQ-8B carries eight (8) APKWS rockets, which it uses in pairs, giving it a total of four (4) attack runs.

      Once the UAV has a target, it will work out an appropriate attack run which will allow it line-of-sight to the target, and launch a pair of APKWS rockets at it. If successful, the target will be automatically removed from its target queue. If not, it will set up another attack run and attempt to engage the target again. In the case of having multiple targets in the queue, it will set up a run on the first target, and once successful, move on to the second, third, etc. If while setting up a run on a target it happens to be able to engage another target further down the queue, it will do so.

    3. Cancelling the MQ-8

      To have the UAV exit the theatre, select the "Cancel MQ-8B" option from the laser designator menu.

  7. Gestures and Chat Control

    The Mk17 can be used for most functions without the HUD. The channel for chat control is channel 5, so 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.
    sling: Will only sling the rifle, not toggle.
    reload: Reloads a magazine or a fresh grenade cartridge in rifle and grenade launcher modes.
    stand: Sets stance to standing.
    kneel: Sets stance to kneeling.
    prone: Sets stance to prone.
    semi: Semi-automatic rifle mode, and will put the weapon into rifle mode if it is not already.
    auto: Fully automatic rifle mode, and will put the weapon into rifle mode if it is not already.
    primary: Selects rifle mode.
    secondary: Selects EGLM mode.
    tertiary: Selects laser designator mode.
    ammo: Pops up the rifle ammunition selection menu.
    glammo: Pops up the grenade launcher ammunition selection menu.
    laseammo: Pops up the laser designator options menu.
    options: Pops up the options menu.
    rangefinding: Toggles EGLM auto range on and off.

    Included in the kit are several gestures you can activate and use for oft-used functions such as drawing/slinging, weapon modes, stances and reloading. The gestures merely use my preferred key bindings, feel free to reassign them to whatever works best for you. However, if you are not using a viewer that allows you to bind gestures to the keys these are, editing the existing gestures will not allow you to save with the current letter and number key bindings.

    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.

  8. Troubleshooting

    1. The Mk17 has been extensively tested and is free of any known bugs. If you believe you have discovered a bug, please contact This email address is being protected from spambots. You need JavaScript enabled to view it. and provide, with as much detail as you can, step-by-step instructions for reproducing it. Things don't get fixed if we don't know what needs fixing. :)

    2. At the time of this writing, there is a known bug with raycasting, as described in SCR-243 which appears to happen to attachments and after a region has been up for 6 or more days. Unfortunately for those without estate controls, the fix for this involves resetting the affected region.

    3. If things aren't rezzing for you, such as the bullets or grenades, check your group tag and make sure it is harmonious with the area you are in, and then detach and reattach the Mk17 to ensure correct group tag propagation.

    4. If you seem to be doing no damage in OCS, first make sure you are wearing a current OCS HUD, and have received a message from the rifle stating that it has activated OCS mode.

    5. Asset corruption happens. Rarely, a copy of something will become corrupt and behave in very strange ways. The first thing to try is to unpack a fresh copy of the item from the box in which it came. If that doesn't solve the issue, you can have another box of the same item sent to you via the service kiosk at The Omega Concern's main store. Failing that, contact the support address and request a new box be sent to you and you will receive it as soon as possible.

  9. The End

    First, a heartfelt thank you to all The Omega Concern's customers over the years. You guys gave me the sweetest gig in the world, and I love you all for it. I do this all for you.

    Product releases wouldn't be nearly as solid as they are without the dedicated testing, suggestions and feedback from Eric Sheppard, Eddison Campbell, Ropemasterdom Skellerjup, and Caete Chevalier.

    As it always has been, and always will be: Fun is the whole point. Do go have some. :)
