The AR-15 started life as the AR-10, designed by Eugene Stoner, Robert Fremont, and L. James Sullivan of the Fairchild ArmaLite Corporation. The AR-10 was chambered in .30-06 and later modified to accept 7.62mm NATO rounds. The AR-15 was developed to be a lighter, .223 / 5.56 NATO version of the AR – ArmaLite 10. ArmaLite sold the rights for the rifle to Colt in 1959. Colt marketed the AR-15 rifle to various military services around the world, including the U.S. with varying results. The AR-15 was eventually adopted by the United States military under the designation M16.
In 1960, General Curtis LeMay was so impressed by a demonstration of the ArmaLite AR-15 that when he was promoted to United States Air Force, Chief of Staff, he requested 80,000 AR-15s for the Air Force. In 1962 the U.S. Army special operations units started using the AR-15 later designated the M16 for special operations in Southeast Asia. Service members reported to have liked the stopping power of the light weight rifle in reports back to the rear. In January 1963, Secretary McNamara received reports that M14 production was insufficient to meet the needs of the armed forces and ordered a halt to their production. The AR15 was the only rifle that could fill the requirements of the U.S. Military. In 1982 the M16A2 was officially adopted as “U.S. Rifle, 5.56mm, M16A2”
The AR15 is an air cooled, gas operated, semi-automatic, automatic, magazine fed, shoulder fired weapon. Later A2 versions were upgraded with round hand guards, an easy rear sight adjustment ‘dial’ and the M16A2 fire selector lever auto selection had been replaced with 3 round burst. Eugene Stoner had implemented a unique modular design that that gave the rifle much flexibility. You can get 7 ½ inch through over 24 inches long barrels ranging in calibers from .22 through .50BMG. The direct gas system does not use the then conventional piston and rod instead it uses the gas tube to feed gases into the receiver. The magazines range from 10 thru 40 double stacked rounds to 100 round drums.
This is a very practical firearm because of its modular design. To me that means that you can purchase one weapon and use the accessories you need to meet your needs for a particular mission. Be it, hunting, home defense, or just at the range plinking away. The AR15 will suit your need like no other firearm can.

We got our steel targets from MOA targets . Man is shooting steel fun! We got 1 – 1/4 inch AR400 and 1 – 3/8 AR500 targets. I threw one of the targets I cut into the mix as well. All 8 inch. By the way, the AR400 I thought I had is mild steel, you will see as the video series progresses.
In a nut shell all 3 handled pistol up to .45 at 10 to 15 Yards without penetration. The Mild had some dents, AR 400 and AR 500 nada.
Here is the Color Code:
Black = Mild Steel, We cut
Yellow = MOA Targets AR500
Orange = MOA Targets AR400
We started lighting up the AR400 ¼ inch steel targets. This is a quick breakdown:
9mm at 15 Yards, 22 at 100 and 150 Yards. Looks good
Here is the 8mm Mouser K98 and 5.56/223 at 100+ yards
And the Gong:
not good, went through it like butter!
There is a lot of talk about steel targets. You can go on line and find enough information to boggle your mind. I decided to go with ¼ inch AR400 steel gongs. These are for my personal use, nothing more. I will post pictures after I light them up.
Here is shot of the 4×8 sheet.
I had to remember how to use my plasma cutter. It was not pretty, but I got it done:
With my Army back, I found it very hard to work on the floor so broke down the plate into smaller lighter sections. With help we put it up on some saw horses to make it easier to cut.
I also discovered these little gems from Swag Off Road. I put the screw and washer in one of the unused holes to create an adjustable stand off. I just adjust for the locations and tighten down the 2 nuts to keep my cutting tip off the steel.
And the bottom. Ignore the scoring:
Greatly improved my cuts:
Here is a shot of the targets for this run:
1 – 20 inch
1 – 12 inch
5 – 8 inch
4 – 6 inch
Drilled 2 holes in each, painted and setup:
Decided to make a shooting bench. I found some very nice plans HERE. Well written and easy to follow.
Here is a shot of my framing job:
Sealed it up before putting the top on:
Cut and added the top and bench:
Finished product with the rubber/mouse pad topper:
Set it up on some stones we had laying around:
Beautified it with some extra metal roofing, filled it with dirt and planted our goodies:
There you have it!
While I am waiting for paint to dry in the shop, I decided to finally convert one of my homebrew keggles to a burn keg. The top is already cut off. I cut rectangles at the bottom to improve airflow. When I was welding on one of the fittings I had a fairly large blow out, when I cut the rectangle it will be like it never happened! I made all the cuts with a 4 inch angle grinder.
Filled the bottom up to the rectangles with sand, put in 2 bricks and set a piece of steel mesh on top of them:
I cut a piece of steel mesh to go over the top as well.
