fire
Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. Slower oxidative processes like rusting or digestion are not included by this definition.
Fire is hot because conversion of the weak double bond in molecular oxygen, O2, to the stronger bonds in the combustion products carbon dioxide and water releases energy (418 kJ per 32 g of O2); the bond energies of the fuel play only a minor role here. At a certain point in the combustion reaction, called the ignition point, flames are produced. The flame is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different.
Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems.
The negative effects of fire include hazard to life and property, atmospheric pollution, and water contamination. If fire removes protective vegetation, heavy rainfall may lead to an increase in soil erosion by water. Also, when vegetation is burned, the nitrogen it contains is released into the atmosphere, unlike elements such as potassium and phosphorus which remain in the ash and are quickly recycled into the soil. This loss of nitrogen caused by a fire produces a long-term reduction in the fertility of the soil, which only slowly recovers as nitrogen is "fixed" from the atmosphere by lightning and by leguminous plants such as clover.
Fire has been used by humans in rituals, in agriculture for clearing land, for cooking, generating heat and light, for signaling, propulsion purposes, smelting, forging, incineration of waste, cremation, and as a weapon or mode of destruction.
I have a new never used bump fire stock that i bought back in March, never pulled it out of the package until now and no longer have any AR's. I have no idea what I paid or what it's worth but will sell for 250 or willing to trade for AK accessories, pm me for any other trade offers. Thank you...
Bought for $275. It's been a safe queen, in the box, ever since. Looking to get what I paid for it OBO. Buyer pays shipping or can meet on central OR coast or in Corvallis area. Don't wait...
I have a used SSAR-15 OGR. Bought it a few years ago when these were first released and used it only a couple of times. I painted it with some krylon FDE but should come off with paint thinner if it doesn’t float your boat. I do not have the original packaging. I never use it so someone else may...
I am making this a separate thread because while it is related, it merits its own thread:

Put those firearms back in the safe, folks! Target shooting is now prohibited in Mt. Hood National Forest, until we get past this extreme/unusual fire potential situation.

I have an sp20rrs with the adjustable buffer. (nra bullseye)
I shoot aguila 38 grain subsonic. Work perfectly for about 3000 rnds.
The thing doubles right in the middle of a match, of course.
Anyone heard anything like this before?
I got a neoprene buffer and tried it, no help.
Had a large brush fire about half a mile from my house....due to a slash burn from recently logged property. Lots and lots of dry pasture could have gone up like kindling if not for our brave firefighters!
This is a Unique VO79 22 short rapid fire pistol in very good condition. I got this off of gunbroker on an impulse and realize it just isn't for me. Had a gunsmith check this out- adjusted trigger position, took grips off to inspect and found all in very good condition, and used a barrel camera...
