Another draft document. Have a look and leave comments so I can make it better. HERE is the link to the pdf
Started building the new range. Started by planting the back 6×6 treated posts.
A little while later, added 2 more on both sides.
Then we started stacking the ties.
A little over half way done.
Got some more done today:
Cut the excess off the top:
We used 10 inch screws to secure the ties to the posts:
I will be using the excess cut from the top to make braces for the back:
Got the angles on the 6×6’s
Planted the support 4×4’s four feet deep and concreted in:
Back Finished up:
I added 2 leftover ties to the corners:
Dropped in some dirt:
Got it pushed back:
Think we are ready to shoot! We will continually make improvements but I think the major work is done.
There are a few areas of consideration when assessing issues with the AR-15 style firearms.
1.) Is the firearm new from a factory? If yes, is it a reputable manufacture, or fly by night?
2.) Is it a new home built? Is this the builders 1st or 50th?
3.) Finally, is this a used rifle that has been fired many times and just started to malfunction?
Ammo and routine maintenance are other items that should be looked at for all 3 considerations. Is it good quality ammo? Hand-loads? Cheap Ammo? When was the last time the rifle was cleaned?
First things first, clear the weapon, make sure it is safe and preform a function check. If the function check fails and it is a new rifle, you might want to send it back. If it is a new home built check that the springs are installed and installed correctly, in the right direction and place. If it is used and just started happening, check for spring wear and replace as needed. The hammer spring is a common culprit of many issues to include intermittent firing, misfires and light fires.
Bad gas can cause a lot of problems like short stroking which can be caused by an improperly staked bolt carrier key coming loose. Another spot to look is if the gas rings are missing or damaged, this is usually on the used rifles. On home built rifles especially, make sure the inlet and the gas port are properly aligned, tightened, and the correct tube is being used. An incorrect or misaligned gas block is a common culprit.
A failure to eject scenario can be cause by extractor and ejector springs. Would not hurt to have a few of those around the shop. Weak springs can cause the spent casing to get caught in the ejection port causing a stove pipe situation. Tell tail signs of ejector/extractor issues are dented cases, round rim markings like scratches or damage to the stamping at the bottom of the round. Inconsistent round ejection is another sign, if you test fire the weapon 3 times and the brass ejects to 3 very different angles, you have an issue. All 3 rounds should end up in a pile close to each other.
Talk to the person bringing you the rifle with the 3 questions above in mind. This will help you narrow down the issue and get the weapon back to your customer quickly. The AR-15 is a reliable weapon and with some initial questioning and test fires as required, you can quickly diagnose the issues and fix it.

The function of the LOWER RECEIVER ASSEMBLY is to house the below items. This is also where the main difference between the AR-15 and the M16 is. The fire control group of the M16 allows either 3 round burst or full automatic fire in addition to safe and semi-auto fire. The AR-15 does not, it has only Safe and Semi firing options.
Lower Receiver – The lower receiver is the part of your rifle that is generally considered to be the firearm itself by the ATF. The lower receiver is where you’ll find your weapon’s serial number. This is also the only part that you will need to get from your local FFL.
Fire Control Group – The Fire control group consists of the trigger and the hammer of your AR-15, as well as other necessary housing components.
Receiver Extension and Buffer Assembly – As part of your rifle’s recoil system, this assembly helps absorb a lot of that kick, making a better shooting experience.
Magazine Catch Assembly – to secure the magazine and allow release when finished.
Bolt Catch Assembly – Is there to lock the bolt to the rear either manually or automatically when the last round is fired and the magazine is empty.
Stock – The butt stock is the part of your AR-15 that connects to the rifle’s firing mechanisms.
Pistol Grip – The pistol grip attaches to the lower receiver, giving you a firm handle of your rifle.
Takedown and Pivot Pin Assemblies – The takedown and pivot pins and detents lock the upper and lower receivers together.
The UPPER RECEIVER ASSEMBLY house the below assemblies and are the same for AR-15 and M16 rifles.
Upper Receiver – The upper receiver is the part that contains the bolt carrier group and charging handle. The barrel and the forend are also attached to the upper receiver.
Barrel Assembly – The barrel will play a huge role in your accuracy on the range or in the field. There are many different calibers and lengths available.
Bolt Assembly – Houses the extractor and ejector assemblies. It locks the breech and initiates the ignition of the cartridge
Extractor Assembly – removes the round from the chamber
Ejector Assembly – Ejects the round from the breech
Bolt Carrier Assembly – consists of the firing pin, bolt, cam pin, extractor and gas key. At a very basic level, the bolt carrier group is responsible for loading your rifle, making sure bullets are fired correctly and ejecting spent rounds from the chamber.
Gas System – Your rifle relies on gas pressure to operate in the way that it’s designed. For the most part, gas blocks are installed on the barrel, inside the handguard. The gas tube connects to the block and the upper receiver.
Charging Handle Assembly – A charging handle is the part that pulls your bolt carrier group to the rear when you need to chamber a round or to clear a malfunction.
Forward Assist Assembly – If for whatever reason your bolt isn’t operating properly and won’t close all the way, the forward assist should help make sure it goes back into place.
Ejection Port Cover Assembly – When it’s closed, the ejection port cover will prevent dirt, dust and other debris from dirtying your rifle, as it keeps both the bolt carrier group and the upper receiver clean
Handguard(s) Assembly – The primary uses of rail systems and handguards is to protect your hand from this heat so you can enjoy a comfortable shooting experience.
Sights – Front and rear sights are alined to aim the rifle.
Magazine – You can get different sized magazines, but it’s important to keep in mind that laws for the size of magazines can vary from state to state.
When all of the above are assembled correctly it will allow for the eight cycles of firing:
All of the above parts and systems have many different variants. This is one of the great things about this platform. You can have barrel lengths from 24 to 7.5 inches with each having different twist rates. Handguards, Stocks and triggers also come in a wide variety of options. Bolt on additions seem to be only limited by your wallet.

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.
Field Stripping can be done with what everyone should have out in the field, a bullet. Might not be the best tool, but in a pinch it will do everything you need to do. First thing you need to do is to remove the magazine, clear the weapon, ensure the bolt carrier group is forward and the safety is on. Set the firearm so the barrel is pointer to the right. Push the rear take down pin towards you, it will not come all the way out and you should feel the upper and lower separate when it is pushed far enough. Now do the same for the front take down pin. You can now separate the upper from the lower receiver.
To disassemble the upper receiver pull the charging handle back and remove the bolt carrier group. The charging handle will drop down as you continue to pull and can be removed from the receiver. On the left rear side of the bolt carrier, you’ll see what looks like a cotter pin, this is the firing-pin retaining pin. Pull the pin straight out and the firing pin will drop out of the bolt. Turn and remove the cam pin the bolt will now slide out. Make sure the gas ring gaps are not lined up and are in good shape. Next remove the extractor pin, the extractor will then come out. Inspect the extractor assembly spring and rubber piece to ensure good working order. Clean everything up with a small cleaning brush and solvent then wipe down with CLP. Re-assemble the bolt by putting the extractor and spring assembly back in the bolt and inserting the extractor pin, return the bolt to the carrier and insert the cam pin and rotate, insert the firing pin and the retaining pin. Run a couple swabs with solvent followed by CLP down the barrel. Insert the bolt group and charging handle to the upper receiver.
The lower assemble contains the trigger group, buffer system and the stock. To remove the buffer and spring, push in on the buffer and depress the retainer pin. The buffer and spring will come out. Clean the buffer assembly, spring, and tube with a swab dampened with CLP. The trigger assembly will require some grease at the pivot points. Inspect the stock for cracks and other damage.
The AR-15-style firearm is a versatile, modular, and easy to maintain rifle that with a little maintenance will last you a very long time.

B.S. (Before Steel) one of our go to targets was clay pigeons. We set them on everything. I saw a plan to use cloths pins and thought I would give it a shot.
Dollar Tree large cloths pins and a box of clays:
I screwed them on a stand I had, turns out the cloths pins I got are too big. We will call this Version 1.0. You can see below the clays are not held securely, I had to put them under the bottom of the pin.
They stood up, still fun to shoot. Just not right. Version 2.0 will be better….
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
