Do you have an attachment class for the rifle?  If you don't then in your rifle class add this in your defaultproperties:

[code:1:a50dcb4e75]AttachmentClass=Class'PACKAGE_NAME.ATTACHMENT_CLASS'[/code:1:a50dcb4e75]

Where PACKAGE_NAME is the name of your rifle packe and ATTACHMENT_CLASS is the name of your class file you will make as ATTACHMENT_CLASS.uc.

In ATTACHMENT_CLASS.uc add

[code:1:a50dcb4e75]class ATTACHMENT_CLASS extends UTAttachment_SniperRifle;

simulated function SpawnTracer&#40;vector EffectLocation, vector HitLocation&#41;
&#123;
&#125;[/code:1:a50dcb4e75]

Look in dFb_Ultra_Rifle_Attachment.uc for an example.  This will get rid of the tracer (the beam that come out of the rifle).

The translocator probably just replaces the impact hammer.  Removing the code just stops the replacement and you end up with an impact hammer instead of a trans.  Although replacement takes a bit more than one line.  I haven't seen the code so I can't give you more other than a guess.
