The AR-15 fires from a locked bolt, meaning that when a cartridge is chambered, the bolt closes behind the case and rotates 15 degrees: the lugs on the bolt head engage the protrusions on the barrel extension, solidly locking the bolt in place, so it can withstand the high pressure produced by powder combustion.

The bullets fired by an AR-15 are different: They travel at a higher velocity and are far more lethal than routine bullets fired from a handgun. ... An AR-15 rifle outfitted with a magazine with 50 rounds allows many more lethal bullets to be delivered quickly without reloading.

Nowadays, almost all military rifles are universally chrome-lined to protect the rifle barrel from excess erosion. AR-15 rifles are particularly prone to erosion when fired rapidly, in part due to the high velocity of the round, and in part due to the high pressures generated by the cartridge.

The plunger works by sucking air and loading the gun barrel with pressure. When the trigger is pulled, the pressurized air sends a dart into a trajectory and the higher the pressure, the faster and farther the dart shoots. ... The gun's barrel is designed with a maze of air pathways where the valves are actuated.

Rifle Buffers: Most rifle buffers on the AR-10 are shorter and heavier than the AR-15 to accommodate the longer . 308 bolt carrier group and the force from a larger round. This means they cannot be interchanged. However, the buffer tubes are the same length, making them compatible with either rifle.

5 Gas Piston The AK-47's combined bolt carrier and gas piston design—taken from a competitor—gives the gun's operating system more energy. As each round is fired, gas rushes into a chamber via a port in the top of the barrel, driving back a piston that withdraws the bolt from the chamber and ejects the spent cartridge.

BCM is in my opinion the current front runner for producing the best AR-15s for the money. While not necessarily the best AR-15 money can buy, all of their parts are extremely high quality, dependable, and light weight at a great price for what you're getting.

The military's M-16 was originally fully automatic, meaning it fired several rounds with each pull of the trigger. Its civilian counterpart, the AR-15, is semiautomatic — the user needs to pull the trigger to fire each shot.

Yes, bolt action AR-15s exist. They are special-purpose and boutique rifles. Not a deep market for them at this time in the USA. Will AR pistol caliber rifles receive the same scrutiny as AR-15 rifles?

The AK-47 is not the most accurate weapon when compared to other assault rifles, such as the M4(AR-15). The accuracy of the AK usually when taken out of the box is steady at 4 inch group. Though over time, changes in its accuracy begin to spread out to 5.8 inch group at 100 yards.

The “AR” in “AR-15” rifle stands for ArmaLite rifle, after the company that developed it in the 1950s. “AR” does NOT stand for “assault rifle” or “automatic rifle.” AR-15-style rifles are NOT “assault weapons” or “assault rifles.” An assault rifle is fully automatic, a machine gun.

AR-15-style semiautomatic weapons are civilian versions of military weapons. So what's the difference? Gun control advocates say the difference is minimal, arguing the AR-15, like its military version, is designed to kill people quickly and in large numbers - hence the term assault-style rifle.
