Ah, never noticed that they restricted what you could put it on. Seems kind of stupid that you can only put it on those weapons, and I'm 99% sure they did it so that people didn't use them on other weapons to negate the penalty for the second shot on SA weapons. I figure any weapon capable of burst or FA fire should be able to have a gas vent. But yeah, you're right, RAW they can't have them, and so you're right, FA pistols are at a large disadvantage.
I'll be honest. I think that rule was an oversight. My guess is that weapon modification rules were created PRIOR to creating the new weapons. Within the SR4 weapons there are only three weapons that fall outside of those categories that support BF and only one that supports FA. Yamaha Sakura Fubuki [Light Pistol], Ares Viper Slivergun [Heavy Pistol], and the Mossberg AM-CMDT [Shotgun] were the three weapons that are BF or FA. Two of these weapons only fire flechette style ammunition, which logically made no sense to have a gas vent as that could cause some of the flechette to scatter sideways or even back at the shooter. The Fubuki fires differently from all other weapons with how recoil stacks and thus gas vent is entirely unnecessary.
The only bit about raw that dissuades me from the interpretation that a weapon needs BF or FA to qualify for Gas Vent is that it doesn't say that firing mode changes allow the modification. Of course, gas vent is a pointless upgrade for any weapon that doesn't fire BF or FA. Regardless, I'm more inclined to houserule that a weapon modded for BF or FA can make use of the gas vent modification.

You can be licensed to carry a sniper rifle. I'm sure it isn't easy, but it is possible. I believe a .50 cal sniper rifle is the most powerful weapon a civilian is allowed to own in the modern USA.
No. All sniper rifles have a forbidden rating while sporting rifles are just restricted. You can carry a sporting rifle with a license. If you get caught with a sniper rifle, you ass will be hauled in do not pass go.
