The AR platform is known to be one of the most modular and customizable weapon systems to exist, and that enables it to be offered in multiple configurations and different calibers. Depending upon the caliber built on the AR15, which entails that significant components must be swapped out, such as the barrel, gas block, BCG (bolt carrier group), and sometimes even the buffer system. The AR-15’s modularity enables it to also shoot its adversaries' rounds, known as the AK-47’s caliber round or 7.62x39. This synergistic hybrid weapon many call the AR47, shoots the larger heavy hitting 7.62 caliber, which lacks in long-range accuracy, but makes up for it in lethal stopping power. The 7.62x39mm cartridge performs exceptionally well at ranges within 300 yards, and its moderate recoil enables rapid follow-up shots, but its performance degrades substantially at further ranges. Both the 5.56mm NATO and the 7.62x39mm have been in use by the military since their inception in the 1960s. The 7.62x39mm is better suited for taking out larger targets at moderate ranges because of its lower muzzle velocity and heavier bullet weights, while the 5.56 is better suited for taking down smaller targets at the same ranges due to its higher muzzle velocity and less to virtually no recoil. This caliber is well known for hunting, self-defense, and other military uses all around the world. The 7.62x39mm variant of the AR-15 has also been developed by a number of other manufacturers. AR-Stoner, Armalite, Colt, Rock River Arms, Olympic Arms, DPMS, Del-Ton Inc, are just a few examples of present and former manufacturers in this industry. Conversion kits and custom fabrications are also offered. The low cost of operation is mostly due to the wide availability and low cost of munitions from a wide number of manufacturers. The bolt, firing pin, extractor, barrel, and magazine are all replaced during a conversion. The AR47 rifle and pistols have more ergonomic advantages than an AK47 due to the fact that they also retain AR controls. The magazine release button is retained, which creates opportunities for faster reloads, and the bolt catch also lets the user put the weapon into battery, or put one round back into the chamber for live fire. These functions have a significant advantage over the more archaic AK47 (AKM47), enabling the AR47 user to increase their target acquisition time and reload speed. If you want to experience the advantages of having a heavier .30 caliber equipped with the 7.62x39 round in an AR platform, then you have come to the right place.
