Compensated GBB's
 

Do compensated GBB's use more gas/use gas faster?

The compensators are for show only.

For the most part. Like silencers they help cover up longer inner barrels, and the extra dead weight on the front of the gun allows recoil to have less effect allowing you to keep sights on the target a little easier.

Your gas consumption should be regulated by the valve on the mag and maybe your hammer spring,the way I understand it.

The compensator uses the gas that propelled the bb forward and redirects it through the ports on the comp in a direction (usually up ) to counter act recoil.
Again ,my 2 cents ;)

you are correct sir

that's real steal only, airsoft comps don't do shit except cover longer inner and add +7 to your bad assedness level.

Naah. It does not interact with the gaz. All it does is add weight to the tip of the gun/barrel with compensates the muzzle climb... which is very light anyways, in airsoft.

EDIT: Grilled.

Nope....in a real gun maybe, but in a GBB it is just a cover inner barrel for the most part...

There sure is hell no holes on top of my inner barrel...

Good to know. Thanks for the info guys :)

Maybe there should be.... o.O

wat?

lulz, just kidding. Obviously there shouldn't holes in your inner barrel. And if there are... well then. I don't really know what will happen if there are. Catastrophic doom, most likely.

You could shoot birds without aiming at them!

Actually, I've read that porting a barrel right can reduce the pressure behind the BB so that it releases more evenly as the BB exits the crown on the barrel.

Dunno if it actually works.

So I'm going to add some info to this thread even though its old.
To the original question, no they should use the exact same amount of gas.

On some compensated guns, it can actually make a difference.
Here is a link to some pics of my gun.. https://www.airsoftcanada.com/showthread.php?t=85611
In this gun (and any frame-mounted compensator, one that is independent of the outer barrel), the inner barrel is held very steady by the compensator. In the Freedom Art long railed frames with compensator on the front, they actually have an O-ring in the compensator that the inner barrel has to go through. This makes the inner barrel stay incredible still, and completely straight with respect to the frame (and front sight, since this is mounted onto the compensator, which is mounted to the frame.

So it doesn't change gas consumption, but if it is a frame-mounted compensator, it can (and should) hold the inner barrel nice and steady with respect to the frame, and just keep it very still in general (since with the o-ring, it actually holds the inner barrel almost completely still at all times) and thus increase accuracy.

Hope this helps some out.

I believe compensators are not generally used except in competition shooting. If you are doing MilSim a compensator should be a no-no.

Comment and correct me please... because I have stayed away from airsoft pistols with compensators because I have believed that it would not represent a valid weapon in a tactical situation.
