These two little puppies are the weapons of choice for my character in Roger Barr's current PBEM.  The one on the left is my Instellarms GRMK-II.  Standard gauss rifle performance in normal mode.  Has a velocity selector switch that's recessed under the stock for switching between hypersonic (normal) mode and sub-sonic.    Switching to sub-sonic effectively makes the weapon completely silent.   Uses a 100 round, helical fed magazine and is equipped with electronic sights and a RAM grenade launcher.  Depressing and holding the safety selector switches the trigger to that of the grenade launcher.  The pistol on the right hand side is the new Instellarms GAP, or Gauss Assault Pistol.  Functions as a normal gauss pistol with the addition of being able to switch to full auto.  Also is switchable between hypersonic and subsonic.

And no, I don't have any stats or figures for the velocity switching.  This is purely a handwave for the fun of it :)

Now, while this weapon is a Photoshop composite of an HK G36 and the M203 grenade launcher, it could easily be used to represent any number of different Traveller ACR designs.

The weapons of the Lucky Credit are 4 laser turrets (don't have Mj right now) and one sandcaster with AV100, 20 cans.
