Kirst looked at the score and smiled, "not bad doc, just above average with a few headshots thrown in. Now we can move on to the different mods." He pressed a button and a large case popped out of the rack. Kirst took it and opened it up to reveal the different mods within. "There are over fifty different mods you can use to make the gun to your liking. There are different barrel lengths, muzzles, suppressors, scopes, sights, stocks, grips, magazines, you name it. Here I will show you my preferred setup." He went back over to his booth and returned with a slightly dirtier MARS rifle. "Mine is customized for general purpose uses. Basically an all-arounder. I have a holographic sight for accuracy, muzzle brake to decrease the recoil, a vertical grip on the front for accurracy, and a double magazine for quick reloads. Lets see what the other guy's guns look like. Hey guys! Its show and tell time for the doc. Bring your mars guns for inspection." The men stopped what they were doing and walked over with their rifles in hand. "Riktof, your up first." Erik walked up and presented his rifle. "Not much different from Kirst's. I have a 4x acog scope for higher magnification instead of a holo sight and a combo laser sight/flashlight instead of a front grip. Everything else is the same." Kirst nodded, "Dante your next." Dante came up and showed off his gun, it was considerably more bulky than the others. "Mine is customized for fire support, basically lotsa bullets. I have an 80 round drum magazine loaded with tracers, air cooled barrel to prevent overheating, an ergo grip to tame the recoil, a cushioned stock, and red dot sight." Up next was Xanders, his was much shorter than the others. "Mine is customized for close quarters fighting like clearing out buildings. It has a short stub barrel so its easier to maneuver. Extended 40 round magazine, a suppressor for stealth missions, and an infra red scope to see through walls. But my favorite is the masterkey." He held up the gun so Cassandra could see the large tube attached to the underside of the barrel. "Its basically a shotgun attachment, its called the masterkey because it shoots specialized shells that can break through locks and hinges." Last up was Turk, his was considerably longer than the others. "Made for long range engagements, counter sniping. Starlight 6x night vision scope, bipod for more stability, extended barrel for more range, 20 round magazine made for large caliber bullets, and a marksman's stock." Kirst nodded, "thanks guys. So as you can see doc, this gun is made with customization in mind. Hell they even have heartbeat sensor screens they use during rescue missions to find people. So feel free to find the mods thats work for you. Once you find the right setup, you can save the loadout specs and any armory can have it assembled for you on the spot.
