其实这个修改在泄露版的时候就搞好了的，现在再来搞一次：
首先，我们先把最底下的这行代码找到：
    <accessory name="AssaultScope" zoommode="assaultscope" category="scope" exclusive="1">
      <attach helper="attachment_top" layer="scope" />
      <detach />
然后打开SCAR的文件依样画葫芦：
     <accessory name="AssaultScope" zoommode="assaultscope" category="scope" exclusive="1">
      <attach helper="attachment_top" layer="scope" />
      <detach />
      <stats_changes stat_accuracy="3" stat_mobility="-1" stat_range="2" GAME="SP"/>
     </accessory>
然后复制，直接把这行代码覆盖。这里有一个很重要的地方，就是要注意accessory这个东西，如果你漏掉了它的话（不管是在上面或下面），就会导致无法进入游戏。
覆盖完毕之后应该是这样：
    <accessory name="GrenadeLauncher" firemodes="GrenadeLauncher" zoommodeSecondary="grenadeLauncherZoom" category="bottom" exclusive="1" enableBaseModifier="1" GAME="MP"  >
      <attach helper="attachment_bottom" />
      <detach />
    </accessory>

    <accessory name="GaussAttachment" firemodes="Gauss" category="bottom" exclusive="1" enableBaseModifier="1" GAME="MP" >
      <attach helper="attachment_bottom" />
      <detach />
    </accessory>       
               
    <accessory name="AssaultScope" zoommode="assaultscope" category="scope" exclusive="1">
      <attach helper="attachment_top" layer="scope" />
      <detach />
      <stats_changes stat_accuracy="3" stat_mobility="-1" stat_range="2" GAME="SP"/>
     </accessory>

    <accessory name="LightShotgun" firemodes="Shotgun" zoommodeSecondary="shotgunZoom" category="bottom" exclusive="1" enableBaseModifier="1" >
      <attach helper="attachment_bottom" />
      <detach />
      <stats_changes stat_range="-3" stat_rate_of_fire="-5" stat_damage="3" GAME="SP"/>      
    </accessory>
（其实不一定要贴这）
好，第一步搞定。接着我们就要在scarab的文件里找到这些代码：
    </zoommode>

    <zoommode name="assaultscope" type="Scope" enabled="0" GAME="MP">

    </zoommode>
再在SCAR的文件里找到ACOG的代码。你会发现SCARAB的代码要短很多，接下来你懂的，直接覆盖。但这里也要注意zoommode这行代码，你如果覆盖，一定要成这个样子：
    </zoommode>

                    <zoommode name="assaultscope" type="Scope" enabled="0" >
      <stereo>
                                <param name="eyeDistance" value="0.002" />

                        </scope>
    </zoommode>
（格式可以不管）
最难的第2步完成了，接下来第3步：
在SCAR的文件里找到：
  <MovementModifiers        speedScale="1.0" rotationScale="1.0" GAME="SP">
    <Ironsight speedScale="0.6" rotationScale="0.5" mouseRotationScale="0.9" coverLeanRotationScale="1.2" />
    <Reflexsight speedScale="0.6" rotationScale="0.5" mouseRotationScale="0.9" coverLeanRotationScale="1.2" />
    <Assaultscope speedScale="0.5" rotationScale="0.2" mouseRotationScale="0.7" coverLeanRotationScale="1.2" />
    <shotgunZoom speedScale="0.6" rotationScale="0.5" mouseRotationScale="0.9" coverLeanRotationScale="1.2" />
  </MovementModifiers>
把assaultscope这行复制粘贴到SCARAB的同位置，得到这样的代码：
  <MovementModifiers        speedScale="1.0" rotationScale="1.0" GAME="SP">
    <Ironsight speedScale="0.6" rotationScale="0.5" mouseRotationScale="0.9" coverLeanRotationScale="1.2" />
    <Reflexsight speedScale="0.6" rotationScale="0.5" mouseRotationScale="0.9" coverLeanRotationScale="1.2" />
    <lasersight speedScale="0.8" rotationScale="0.4" mouseRotationScale="0.9" coverLeanRotationScale="1.2" />
    <Assaultscope speedScale="0.5" rotationScale="0.2" mouseRotationScale="0.7" coverLeanRotationScale="1.2" />
    <shotgunZoom speedScale="0.6" rotationScale="0.5" mouseRotationScale="0.9" coverLeanRotationScale="1.2" />
  </MovementModifiers>
接下来就检查一下，照这上面的这些来，确定没有错误之后（记着备份）保存，进入游戏。哈！我们可以发现武器自订—瞄准栏那里已经多了一个assaultscope，装上开爽吧。
