Ever heard anybody bitching about it? They (gas pistons, not necessary "short stroke" ones) are on the M249 and M60, as well as many other light machine guns and assault rifles. It's pretty much a self-enclosed system, like a shock absorber.
That gives me an idea. Maybe the piston could largely be replaced by a cylinder of non-compressible gas! I wish I wasn't too lazy to check to see if that's been patented. |
A non-compressible gas? That would be a liquid surely. |

Yes, a fluid, rather. Gases are all compressible. And, if you used a fluid, the weight savings would be negligible.
On the other hand, a gas might be useful in that it would function as a low-weight shock absorber, possibly serving to dampen the recoil to just the amount of force needed for reliable charging of the bolt assembly; this could eliminate the need for a recoil buffer spring, which would further reduce weight. This could even be adjustable, to compensate for temperature and altitude, if the gas were air.
I guess it would be simpler and more idiot-proof to just find a better way to vent the gases, so they stay outside of the receiver. I think the only way to do that without adding a lot of weight would be a short piston at the end of the gas tube, which would act on the bolt carrier where the gas-key currently is. I think that would only add a few grams.

Awesome. Now we need a full briefing on the weapon and its features, followed by a demonstration of marksmanship and spectacular destruction. Not encouraging that "cheap ammo" didn't work, though.

Shouldn't you wearing some safety gear?

You want one of these (7.62 NATO combat rifle, such as the FN FAL or a modern M14 variant):

The safety gear is the Marine between the ears.

Actually this looks pretty kick-ass right here (incredibly accurate, although the ammo would be hard to come by in a survivalist scenario).

It's very similar to a .308, but with that, someone who knows how to shoot will hit something about 5 times as far away as the FN FAL, but it's still as generally useful. This is a good weapon for somebody who wants to fight like a sniper, but doesn't want to carry two weapons.

My Browning A-Bolt in .338 Win. Mag. with a 190 grain bullet, using Nikon optics will reach out and touch something.

Yes, indeed. Good elk guns are basically sniper rifles. 
You don't see those around here, except for the survivalists, because the biggest thing you can legally hunt is deer (which that would destroy).

/me skims through the last few posts. Don't see a video. Cannot care.
/me sees mention of FN-FAL. /me approves.

FN-FAL works well from atop an elephant, but it won't stop one.

Brave warrior Old School: I release you from the bet early because you alone had the courage to put your potatoes on the table and face me in battle. Others talked big but, when push came to shove, they simply fled.
Plus you've got an elk gun and I don't want to spend the rest of my life looking at the wall thinking: is that really thick enough?
Go in peace! Your deeds will always be known amongst my people  |

On a serious note, elk is delicious.

Also on a serious note, unless it's a cinderblock wall or better, or unless you're behind the engine block, then no, that's not thick enough.
