Tungsten alloy shot is made of tungsten alloy. High density, great hardness and resistance to high temperature make tungsten alloy to be one of the most sought -after material for shotgun pellets. Density of tungsten alloy shot is about 18g/cm3. Tungsten alloy shot is used as pellet of MKA 1919.

MKA 1919 is a gas operated, semi-automatic shotgun that resembles the M16 rifle and mimics the layout and placement of some of the controls. It was created by Turkish company Akdal Arms. The MKA 1919 uses a conventional gas-operated action which is located around the support tube that runs below the barrel. The return spring is also located around the same support tube which is concealed by an enlarged polymer handguard. The MKA 1919 barrel can be quickly removed from upper receiver. To charge the shotgun, the charging handle on the receiver must be pulled. The upper receiver is manufactured from an aluminum alloy while the lower receiver, along with pistol grip and shoulder stock, is manufactured as one piece from impact-resistant polymer. Akdal MKA 1919 semi-automatic shotgun has a 5 round detachable box magazine. It has a bolt release identical in location and function to the one on the M16. Manual safety also duplicates M16-style being located on the left side of the receiver above the pistol grip. Standard sights include a front post installed on the M16-style removable base and a detachable M16A2-style carrying handle with built-in diopter sight. On the upper receiver, an integral Picatinny rail can be placed which will accept detachable carrying handle or optional red-dot or other optical sight attachments.

Using tungsten alloy shot, MKA 1919 can penetrate wall or door and has good performance.

Buying gold can be a great long-term investment, as long as you're buying real gold. Gold is a valuable commodity, which attracts people who wish to make some money through counterfeiting. The best way to determine whether your gold is fake is to go to a jewelry store and have it tested, however this may cost you some money. Alternatively, before you venture out to go buy gold, learn a few simple ways of determining whether the gold you're looking at is real or fake.

1.Put the magnet next to the gold. Real gold will not be attracted by the magnet, however fake gold or gold-plated metal will be attracted.

2.Rub the gold with a jewelry cleaning cloth. If the gold is fake, a few hard rubs will remove the plating.
3.Place the gold into sterling silver cleaning solution. After a day, real gold will not oxidize, however plated brass will.

4.Rub face powder onto your arm using a powder pad. Rub the gold against the powder on your skin. If it makes a black mark, it is real gold or gold-plated.

Gold is used around the world as a form of money, an investment tool and as jewelry. It is also valued for its beauty, resistance to corrosion and conductivity of electricity. Other materials look like gold but are not as valuable. Fake gold is sold in markets around the world, and it is easy to get fooled. You can do tests at home to know whether your gold is real.

1.Place a magnet next to the item that you think is gold. Pyrite and similar materials will be attracted to a magnet. Gold does not have magnetic qualities and will not be attracted to the magnet.

2.Scrape the item across a porcelain tile in a straight line. If it leaves a black line on the tile, the item is not real gold. If the line is gold colored, the item is probably true gold.

3.Find an item that you are sure is gold and is exactly the same size as the item you are testing. Hold one item in your left hand and the other in your right hand. The items will have the same weight if they are both gold.
