An assault rifle is a selective fire rifle that uses an intermediate cartridge and a detachable magazine. Assault rifles are currently the standard service rifles in most modern armies. Examples of assault rifles include the StG 44, AK-47and the M16 rifle.
The Germans were the first to pioneer the assault rifle concept, during World War II, based upon research that showed that most firefights happen within 400 metres (1,300 ft) and that contemporary rifles were over-powered for most small arms combat. They sought to develop a select-fire intermediate powered rifle combining the firepower of a submachine gun with the accuracy and range of a rifle. This was done by shortening the standard 7.92×57mm cartridge to7.92×33mm and giving it a lighter 125 grain bullet, that limited range but allowed for more controllable automatic fire. A smaller, lighter cartridge also allowed soldiers to carry more ammunition "to support the higher consumption rate of automatic fire."
M4A1
The M4 carbine is heavily used by the United States Armed Forces and is replacing the M16 rifle in most United States Army combat uints.[7]
The M4 is also capable of mounting the M203 grenade launcher. The distinctive step in their barrel is for mounting the M203 with the standard hardware. The M4 is capable of firing in semi-automatic and three-round burst (like the M16A2 and M16A4), while the M4A1 is capable of firing in semi-auto and full automatic (like the M16A1 and M16A3).
The M4 carbine is a shorter and lighter variant of the M16A2 assault rifle. The M4 is also a 5.56x45mm NATO, air-cooled, direct impingement gas-operated, magazine-fed assault rifle. It has a 14.5 in (370 mm) barrel and atelescoping stock.
M16A4
It is an M16A4 rifle, with the upper receiver of an A4 and lower receiver of an M4 Carbine. It is capable of fully-automatic fire, but semi-automatic fire allows for more accuracy and conserves ammunition, a very scarce commodity. It has a collapsible fore grip under the barrel.
In 1963, the M16 entered United States Military service and was deployed for jungle warfare operations during the Vietnam War. In 1969, the M16A1 replaced the M14 rifle to become the U.S. military's standard service rifle. The M16A1 improvements include a bolt-assist, chromed plated bore and a new 30-round magazine. In 1983, the USMC adopted the M16A2 rifle and the U.S. Army adopted it in 1986. The M16A2 fires the improved5.56×45mm NATO (M855/SS109) cartridge and has a new adjustable rear sight, case deflector, heavy barrel, improved handguard, pistol grip and buttstock, as well as a semi-auto and three-round burst only fire selector.
The M16 has also been widely adopted by other militaries around the world. Total worldwide production of M16s has been approximately 8 million, making it the most-produced firearm of its 5.56 mm caliber.[20] The U.S. Army has largely replaced the M16 in combat units with the shorter and lighter M4 carbine.
Smith & Wesson M&P 15 Sport
The Smith & Wesson M&P 15 Sport is designed for just that Shooting sports. It is also ready to take on any other AR job description, personal defense, target, home protection, varmint hunting or just plinking. Featuring 16" barrel, an adjustable or adjustable style stock, adjustable front and Magpul folding rear sights, chrome lined gas key and bolt carrier. It also features a 30 round magazine or a 10 round magazine. You can also get the 10 round fixed magazine with a bullet button for the stated that the other is not legal.
The M&P 15 lower and upper receivers are made from 7075 T6 Aluminum, fully forged in house by Smith & Wesson. Included with the lower: the single piece, solid forged, non-removable, over sized for gloves trigger guard. A typical six position telescoping stock is standard, along with sling mounts allowing for single or double point sling attachment. There is even a bayonet lug just in case. All of the M&P15 Sport’s parts are interchangeable with the rest of their AR15 product line
The M&P15 Sport’s barrel isn’t an M4 cut. This cut in the barrel will allow to mount a M203 grenade launcher. This additional cut also does not help the harmonics of the barrel. We think this a advantage that will help accuracy but will ultimately come down to the ammo used.
The Smith sports a full profile barrel of American 4140 Steel. The bolt carrier and gas key are chromed, and the barrel sports their Melonite coating. Smith claims that the bare bones approach has no effect on durability. There have been reviews with this rifle firing 85,000 rounds of various brands of ammunition without any visible damage to the Melonite finish. We have found this to be a very reliable platform and so have law enforcement and countless other agencies.

AK 47
After the war in 1946, the AK-47 was presented for official military trials. In 1948, the fixed-stock version was introduced into active service with selected units of the Soviet Army. An early development of the design was the AKS (S—Skladnoy or "folding"), which was equipped with an underfolding metal shoulder stock. In 1949, the AK-47 was officially accepted by theSoviet Armed Forces and used by the majority of the member states of the Warsaw Pact.

It is officially known in the Soviet documentation as Avtomat Kalashnikova (Russian: Автомат Калашникова).
It is officially known in the Soviet documentation as Avtomat Kalashnikova (Russian: Автомат Калашникова). It is also known as Kalashnikov, AK, or in Russian slang,Kalash.
Even after six decades the model and its variants remain the most popular and widely used assault rifles in the world because of their substantial reliability under harsh conditions, low production costs compared to contemporary Western weapons, availability in virtually every geographic region and ease of use. The AK-47 has been manufactured in many countries and has seen service with armed forces as well as irregular forcesworldwide, and was the basis for developing many other types of individual and crew-served firearms. As of 2004, out of the estimated 500 million firearms worldwide, approximately 100 million belong to the Kalashnikov family, three-quarters of which are AK-47s.
The AK-47 is a selective-fire (semi-automatic and
