Gun History

Did you know? Guns didn’t always look like they do now. The first known “gun” was a bamboo tube using gunpowder to propel a spear and appeared in China at about 1000AD. The Chinese invented gunpowder in the 9th century.

The Fire Lance

The fire lance was an early form of a firearm. It consisted of a black-powder filled tube attached to the end of a spear and used as a flamethrower. Occasionally, the barrel held shrapnel and would fly out with the flames. Over time, the amount of saltpeter was increased to provide a greater explosive force and metal replaced paper and bamboo barrels as a direct need of increased explosive force.

The Projectile

Later, the projectile replaced shrapnel and more fully filled the metal tube. This provided the metal barrel, high nitrate gunpowder, and a projectile occluding the muzzle which allowed the powder charge to provide a guns propellant potential.

Gunpowder & Handheld Cannons

Gunpowder came to Europe by the 13th century. The oldest known firearm in Europe was found in Otepaa, Estonia and dates to 1380 or earlier. In Italy during the late 13th century, Italians developed small portable handheld cannons, creating the first smooth-bore personal firearm.

During the early years of the modern age, these personal hand held cannons developed into the flintlock rifle, which then evolved into the breech loader and lastly into the modern automatic weapons of today.

Fixed Ammunition & Civil War

The paper cartridge was developed in 1586 and, by 1850, brass was used for fixed ammunition. Repeating firearms was the next innovation with repeating revolvers. The first successful rapid-fire firearm was the Gatling gun, invented by Richard Gatling and used by the Union forces during the American Civil War. At the time, it required four men to operate it and subsequent upgrades saw it used in the Spanish American War. However, its unreliability on the battlefield resulted in its retirement.

Guns in America

America and guns grew up together. The advances in firearms at the hands of Americans grew faster than what came before. American gun legends were born and American ingenuity had begun with a rapid succession in inventions and innovations that would change the world.

Through the ages, guns have grown increasingly sophisticated and continue to do so year after year. From a bamboo tube “gun” to modern firearms able to acquire targets, the ages offer a peek into the future.

Which Caliber is Better? .223 Vs. 5.56

Posted on  | 0 Comments

.223 vs 5.56 AR-15 For Sale

It occurs commonly when a buyer chooses an AR-15 for sale chambered for .223 caliber and expects to shoot 5.56 ammunition in it. After all, many manufacturers actually print both calibers on the rifles, and it is in the manual that came with the rifle. So it is okay, right?

Unfortunately, the answer is no. The 5.56 will fit into the .223 chamber but, beyond this, the 5.56 in a .223 chamber is going to create problems. The cartridges may look the same, but the 5.56 Mil-Spec is hotter ammunition than .223. That is to say, the 5.56 has a higher chamber pressure. The chamber on the .223 is actually smaller, though not enough to prevent it from being inserted. It is small enough that it prevents the 5.56 case from expanding as it would in a 5.56 chamber.

What’s The Problem?

The firing of 5.56 ammo in a rifle chambered for .223 causes primer blow back to enter into the receiver decreasing reliability, as well as an increase in failures to eject spent cases. That is due to the hotter load of the 5.56. You may even have to use a rod down the barrel to remove the casing. Firing Mil-Spec ammunition may also crack the receiver posing a real hazard to the shooter and everyone nearby. It is far safer and provides greater reliability to purchase an AR-15 for sale chambered for 5.56 caliber ammo to begin with.

Different Chambers

Technically, you can fire 5.56 ammunition in a rifle chambered for .223, but why ruin the rifle and endanger yourself and others? If you want to use 5.56 Mil-Spec, buy a rifle chambered for 5.56. Basically, there are three types of chambers for AR-15 family of rifles.

  • The first is the Mil-Spec 5.56 chamber used in the M16 and M4.
  • Second is the .223 chamber commonly found in the AR-15 rifles.
  • Third are the .223 Match chamber, commonly used in AR-15s by competition shooters.

The common .223 chamber are manufactured to Sporting Arms and Ammunition Manufacturers Institute Specifications (SAAMI). This chamber is ever-so-slightly smaller and tighter than Mil-Spec 5.56 chambers.

Match Chamber

The match chamber is the preferred chamber for professional competition shooters. Match chambers are not chrome lined.

The preferred weight of ammunition for match shooters and snipers is 77 grains and above. This ammo is slightly longer and lighter than AR ammunition. Using this grain of ammunition is not a problem in a rifle with a match chamber, but if you try to use it in the common .223 chamber problems occur due to the extra length. The extra length causes spillage of powder on the receiver and magazine when ejecting an unspent cartridge. To avoid the problems that may cost you a competition, purchase a match caliber .223 AR-15 for sale.

Mil-Spec Chamber

Mil-Spec 5.56mm chambers are always chrome lined in M16s and M4s for military use and typically are for the AR-15 equivalents. The 5.56mm Mil-Spec is slightly larger than common .223 SAAMI spec. This is due to the 5.56mm Mil-Spec being loaded hotter and having a higher chamber pressure.

Whereas it is highly discouraged to use 5.56 in a common .223 chamber, it is allowable to shoot the .223 ammunition as well as the 5.56 out of a rifle chambered for the 5.56 caliber, without any of the reliability or safety concerns of a .223 chamber. Just keep in mind, the .223 ammunition may not provide quite the accuracy at long distance as the 5.56 ammo. The .223 caliber ammo is slightly smaller and doesn’t fire as hot or with as much pressure. Plus the bore of the 5.56 is slightly larger. This advantage prevents the problems that may occur when ejecting a live cartridge, as can occur in a rifle chambered for .223.

Which Chamber Should I Buy?

If you are considering the purchase of an AR15 for sale, you may be wondering which chamber you should buy. If you are only going to be firing SAAMI ammunition, you can choose a common .223 AR-15 for sale. You should not fire 5.56 in a common .223 chamber.

If you participate in competition shooting, do not choose the common .223 SAAMI chambered AR-15. You will need the .223 Match Chamber AR-15 for sale in order to efficiently fire the required ammunition.

Finally, if you ever plan to shoot 5.56 mm Mil-Spec, you should purchase an AR-15 for sale that is chambered in 5.56. With the rifle chambered for 5.56 ammo, you will have the option of firing .223 ammo safely. The 5.56 chamber is the only chamber with this versatility. So if you have any thoughts of ever having to fire 5.56 ammunition, be safe and take the path that covers your bases. Purchase the AR-15 for sale chambered in 5.56.

Which is Better? The AK47 Vs. The AR15

ak47 vs ar15

AK-47 and AR-15’s | Head to Head

There are fans on both sides of the AK-47 vs. AR-15 debate. Depending upon the intended use, each gun has its advantages. When making the decision as to purchase the AR 15 for sale vs. the AK47 for sale on today’s market there are several factors to be considered. One way of looking at it is that you are comparing the larger 7.62 × 39 caliber to the smaller 5.56 × 45 and .223 caliber.

Caliber is Important

Unlike the 5.56 caliber, the 7.62 caliber is able to penetrate a concrete block, or as much 0.5 inch steel plate, depending upon the ammo used. The 7.62 is going to do more damage.

All 10 bullets of both the AK and the AR 15 penetrated both sides of a truck, but only the 7.62 ammo went completely through two plywood walls of a garage. As for the 5.56 ammo, 7 of 10 shots fired entered the first wall and fragmented after passing through both sides of the trucks metal body. The results of this demonstration was in the fragmentation of the AR15 in the first wall with only three entries of ten into the second, whereas all 10 shots of the AK47 went clean through everything.

Just this past fall I saw on the news that a hunter had killed two deer with one 7.62 shot as the bullet passed through the first and entered a second killing both. Luckily he wasn’t at the end of his seasons bag limit as it was caught on film. Never under estimate the power of these guns, or of any gun for that matter. It is a gun owner’s responsibility to know the proper use and handling of a gun, as well as knowing a guns range.

Applications of the AR-15 Vs. AK-47

For the gun with the tightest grouping, the longest range, one you can trick out to the max, or use in competitive shooting; choose the AR. But if you want a rifle for self-defense and the greatest reliability, choose the AK 47. Practice makes perfect and the more familiar you are with any gun, the greater your accuracy will be. Using a good grade of ammo for sale will also help.

The AK vs. AR debate includes suitability for home defense. I personally would never shoot either inside of my home. They are simply too powerful with the ability to pass through an assailant or the walls. Either could also pass through an exterior wall and into a neighbor’s house. I prefer the AR-15 as a coyote gun and the AK is one of my if-crap-hits-the-fan guns.

Hunter’s use both guns with success and there is no shortage of either in the woods come deer season. Ultimately, my advice is to shoot both weapons before making a decision. Both are great guns and, if you can afford it, purchase one of each. I have seen accurate hunters take a deer in one shot with a .22 rifle. It’s just proof to the old saying that “a good gun can’t make a good hunter out of a bad one.”

Weight of The AK47 vs. AR15

Another factor to consider in the AK-47 vs. AR 15 decision is weight. The heavier AK 47 for sale is manufactured out of steel, whereas most AR’s are manufactured from mostly aluminum. Due to their larger size, the AK-47 ammo will add more carry weight than the AR-15 ammo for sale, another reason that many choose the AR over the AK.
