MACHINE GUNS AND CANNONS
All machine guns and assault cannons can be equipped with
top-, barrel-, and underbarrel-mounted accessories, unless otherwise
noted. They cannot use silencers or sound suppressors and
suffer from double recoil modifiers (see Recoil, p. 152, SR4A).
Firing these weapons requires the Heavy Weapons skill.
So no silenced Guass Rifles or suppressed MGs.
Of course you can always take a barrett, slap a large Firing Mod: Full-Auto on it, pop Electronic Firing in it and a Sound Supressor, Shock Pad, and Gyro Stabilization Harness on it for a nice anti-armored troll weapon.
hey guys, don't mean to be a rules whore here, BUT.... if you're playing by 4th ed rules the entry on page 152 reads as follows.,
Any weapon classified as a Heavy weapon (light, medium, and heavy machine guns and all assault cannons) has all it's uncompensated recoil doubled. For example if a medium machince gun fires a 6 round burst it only has 3 points of recoil compensation (reduceing it's recoil modifier from -5 to -2), it's final modifier would be -4 (-2x2=-4). Any Shotgun fired in burst mode also doubles the modifier for any uncompensated recoil.
The uncompensated part is the most important bit in there. which means it's not all the recoil from base, it's only the uncompensated stuff that's doubled up. which makes a HUGE difference. (I spent 2.5 hours trying to cram the most recoil comp I could into a panther XXL so that It could fire full auto, but still not suffer recoil modification. My GM pointed that rule out to me and saved me plenty of frustration.)
Sounds kinda like the sniper rifle that Sarah Connor puts into full auto during the assault on the computer guy's house in Terminator 2.. only much, much bigger
That actually wasn't a sniper rifle. It was an M16A2 with a laser sight barrel attachment and a scope mounted over the iron sights held in place by a screw mount, modified for SA and FA. I say this because the magazines used in the weapon seen during that scene were made to fit 5.56x45mm rounds. It is true that Back in 1996 there was a DMR, verison of the AR-15/M16 design, but it was chambered in 7.62x51 and wasn't widely used. (to my knowledge.) much less capable of FA selection. Gun freak/
