Hi all

Was wondering if its possible to remove Gas Vent systems once
installed. Are they a permanant feature or can you exchange them with
a silencer in a few seconds? Any help would be appreciated.

I don't have a book with me right now but I believe it states right in the
description of gas-vents (at least in the SR II book) that gas-vents can
not be un-installed once installed.

Something I'm wondering here. Gas Vent systems and silencers are
completely opposite in the way they treat compressed air, right? The
silencer using the compressed air to muffle the shot, and the gas vent
using the air to handle recoil, or something like that? So how the
heck can the Ranger Arms sniper rifle have a combined silencer/gas
vent-II?

Depends on the weapon. On an M16A2, for example, you can unscrew the thing
(which, in SR, would be rating 1, or maybe 0) but you're not allowed to in
the US Army. On the other hand it is also easily possible to machine a gas
vent into the end of a barrel (as is the case with some target pistols,
AFAIK).

In SR, though, I figure that any gas vent is removable -- if not with a
screwdriver, then with a hacksaw.

And yes, I am aware that in SR3 (page 280) it says that gas vents cannot
be removed once installed. I don't see why they would be designed that
way, though...

Gas Vents direct the gas in a way to stop the weapon "climbing".
Silencers expand and cool down the gas to prevent the bullet from going
hypersonic and producing the "crack" _and_ to alter the sound of a fired
shot to make it harder to detect the firing of the weapon.
With the Ranger Arms SM-3, the gas vent would just be located
behind the silencer.

I would guess that Gas Vent systems involve replacing integral parts of
the weapon. If this is true then uninstaling would mean replacing most
or all of the removed parts. It could be that because of this, replacing
the weapon my be easier, cheaper, or otherwise more desirable than
removing the gas-vent.

I figure its just one of those "easy fixes" like the "can't mix ammo in a
clip"ruling.
For example, on a colt 1911, you can get a replacement bushing that acts
as a compensator (I'd say rating 1)
for 60$, an easy drop in part.

The actual venting of the barrel, which would not be removable, would
also not subtract from concealment, since drilling holes in a barrel does
not make it bigger in anyway :-)
This being why I added some rules for it on my site.

OK, I'm no firearms expert, but wouldn't that mean that a combined gas
vent/silencer system *is* possible? Or did FASA kinda make an 'oops'
with the rules here? Or is it that the silencer on the Ranger Arms is
less effective than a 'true' silencer? Does a sniper rifle even need
one? My reasoning being that you don't exactly hear the CRACK of a
rifle from 700 meters off and say, "Ah-hah! I heard gunfire!" That
sniper can be anywhere, and at 700 meters, you're a bit far from any
sort of retaliation small arms can offer unless, of course, it's
another sniper rifle.

that is what counter snipers rifles are for, yes :-)
as for whether you can cobine the two gas systems, I think not in the way
they are presented, though I think a system could be made that duplicates
the recoil reducing effect.
Note: why reduce the recoil on a sniper rifle? how often will the gas
system be used?

A real life gas vent functions by venting the gas to counter the recoil,
this actually make MORE noise than without the gas vent and in most cases
more flash too.

As I understand it, you don't hear "the CRACK of a rifle" at all unless
you break it over your knee. Instead, what you hear is the supersonic
crack of the bullet. (Some/Most/All?) sniper rifles use *subsonic*
rounds which are significantly quieter. At the extreme range of a sniper
rifle, I doubt you tell where the sniper is by the sound of the shot even
if the rifle is unsilenced ...

As for how the Ranger Arms can have Gas Vent AND a silencer, instead of
having one follow the other (which I doubt works), can you combine the
two? In other words, can the Gas Vent have integral baffles to slow the
gases to subsonic speeds?

I would say this is true for military sniping. I swiftly read a book about
snipers and IIRC there is a world of difference between military snipers and
security/police snipers.

The difference is due to the circumstances in which they operate: the
terrain military snipers use, indeed allow you to have a distance of 700
meters of more between you and your target, while security/police snipers
often don't have this luxury. Although I thought security/police forces
really have to worry about the CRACK of the rifle, I would say that
silencers might come in handy, because distance between the sniper and the
target is much smaller.

I don't recall specific details about the tactics used by both forces, but I
do remember that they were completely different because of the terrain of
operation and the goal to be obtained.

Just my thoughts,

Wouldn't you hear "the CRACK of a knee" instead? :)

Some, and a very small number at that. Subsonic ammo does not go together
well with accurate, long-range shooting.

I guess this thing is some kind of sound suppresser that has gas vent
holes cut into its forward (furthest away from the barrel) chamber(s), so
that gas is vented up to counteract the recoil, but only once it has
reached a subsonic velocity.

Most certainly.

OTOH, police snipers are usually there to fire one shot, and once they've
done that the job is over, because the criminal is dead. Military snipers
have to leave the target area undetected; a silencer should help in that,
especially if there are unfriendly troops nearby.

Police (and criminal) snipers tend to go to high ground where they have as
good a view of the target as they can get, and sit around there until the
situation has been resolved by one means or another. They don't have to
worry about sneaking around too much, because they only have to stay
hidden from the intended target. Once the situation is over, the sniper
can simply get up and walk away.

Military snipers find a place that allows them to observe the target
unseen (sometimes for weeks on end), set up a shot, and has good exit
routes that allow the sniper to get away undetected after firing. They
also have to remain undetected by _everyone_ because they usually operate
deep in enemy terrain, and against snipers, the Geneva Conventions often
don't apply in the eyes of enemy soldiers...

Add in that most sniper rifles fire 7.62x51mm NATO aka .308 Winchester
rounds.....

First off, the Ranger Arms SM-3 is a joke if you're out in the field rather
than in the sprawl. The modular design is great for a sniper-on-the-go,
but the SM-3 doesn't have any durability, unlike certain RL sniper rifles
that use a modular design. At best, it's effective for police/SWAT
snipers. Anything else, forget it. :)

And if I see the word Barrett mentioned as a 'sniper' rifle one more time,
I'm gonna puke. The Barrett is an 'antimateriel' weapon. Aka a weapon to
blow out radiators from 500m. Most definitely *not* a true sniper rifle :)

The question was "how does the combined gas vent/suppresser work?" This is
my theory of how it might work.

The problem is that "venting" vector hypersonic gas in a direction
opposite to recoil motion. I suppose it could (possibally) vent / vector
the gas into a sourouding baffke, but that seems inconvienient. The more
likely method would be to use and "internal vent" that turned some of the
gas energy into mechanical energy, which is something most automatics do,
more or less well. That could work with a silencer.

If it vents gas behind the silencer, isnt't that gas going to make a

You may not worry about the target hearing the sound, but if your
sniping from a book depository, you don't want the depository employee's to
hear you and call the cops...

I don't think so. The gas is already cooled
down and subsonic, and the only thing you do is
creating a second opening at the end of the barrel.
It won't produce more noise than the end of the
barrel itself [you know, where the bullets exits,

Ah, by "behind", you mean "downstream". I genrally consider the
front
of a gun (called the muzzle) to be the end the bullets come out, making
"behind" the silecer a bad place to vent gas if you want the silencer to
work... Damn prepositions.
OK, but isn't venting cooled, slow moving gas going to be pretty
ineffective at producing a counter-recoil force? The point of a slincer is
to reduce muzzle gas energy, which means theres not much left to counter
recoil force.
I think some internal mechanism (like a nice meaty slide / bolt /
whatever it is moves back while the bullet goes forwards) woud be a better
bet for countering recoil but keepig the gun quiet. If nothing else, it
could reduce "felt" recoil, by spreading the impulse out over time, and it
would not affect noise (in fact, by absorbing gas energy, it would make the
silencer's job easier).
