gas
Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture would contain a variety of pure gases much like the air. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colorless gas invisible to the human observer. The interaction of gas particles in the presence of electric and gravitational fields are considered negligible as indicated by the constant velocity vectors in the image. One type of commonly known gas is steam.
The gaseous state of matter is found between the liquid and plasma states, the latter of which provides the upper temperature boundary for gases. Bounding the lower end of the temperature scale lie degenerative quantum gases which are gaining increasing attention. High-density atomic gases super cooled to incredibly low temperatures are classified by their statistical behavior as either a Bose gas or a Fermi gas. For a comprehensive listing of these exotic states of matter see list of states of matter.
Hey all,
Selling an ALG EMR v3 15" rail
It's in what I'd describe as "very good" condition with only one small blemish on the right side. However, it has had a hole drilled on the right side to allow access to an adjustable gas block. I understand aftermarket modifications are not...
I bought a new AR15 SAA pistol upper with a clamp on gas block that keeps coming loose because the two clamp bolts keep pulling out the aluminum threads (third time now) SSA fixed it under warranty but not so sure they want to fix it again, said they will call me back when they make up their...
Hi everyone,
I was wondering if anyone could recommend a local AR gunsmith to install a pinned Giessele Super Gas Block on a new barrel. Some drilling will definitely be required. I don't have the tools to do this myself and would like it to be done properly.
I haven't had a ton of luck...
Running into a little trouble with getting a gas tube to fit on my Vepr 7.62x39.
First I had to dremmel the front of the new gas tube (brand new russian unissued from Carolina Shooters Supply) which is pretty normal from what I could find on line. Now I can't get the gas tube locking lever to...

I have a polymer 80 lower I won't be using. It is black and comes just like it does directly from polymer80 with box, bits, jig, etc. It was shipped to me as a blem model but looks pretty good to me. $50 shipped.
I also have a gas block front sight I removed from my BCM M4 upper. Practice...
In Range TV had an interesting video on vintage Civil Defense masks. In this case, the somewhat creepy* children's Mickey Mouse one. Anyway, I found it interesting and thought I'd pass it along.
*It wasn't just me that though it a little weird. My four year old was wandering around and...
i have several ex-government generators that I really should sell. There are 3 7.5 KW gas units mounted on trailers. These are real 7.5 100% duty cycle machines built on nice large tire trailers. I bought them all at the same time from the State of Oregon when they went to diesels. They are...
