Principle of operation of the carbine
The AR-15 Son of Gun platform is based on the classic gas system developed by Armalite. It uses gunpowder gases that, through a hole in the barrel and then a gas tube, enter the interior of the slide, expanding it and unclamping it. The advantage of such a system is the reduced weight of the moving assembly, reduced recoil sensation and smooth operation of the breech. The weapon is bolted by rotating the breech face with 6 symmetrical bolts. The breech and trigger chamber, standard for AR-15 carbines, is made of milled aluminum coated with a durable coating created by the anodizing process.
The 12.5-inch precision barrel
The SOG AR-15 is equipped with a 12.5-inch-long barrel, which allows efficient maneuvering in confined spaces. Its surface has been subjected to a nitriding process, for protection against harmful factors such as the corrosive effects of gases produced during the combustion of gunpowder. The barrel ends in a thread with a factory-installed "Birdcage" flame suppressor.
The front bed is equipped with the M-LOK mounting system
The SOG AR-15 carbine uses a hexagonal front bed with angles at 3, 6 and 9 o'clock and holes in the M-LOK standard. With their help, you can easily install additional equipment like a flashlight, foregrip, angle grip or additional sighting device. Through the entire length of the lock chamber and the bed is drawn a 22mm rail for mounting sighting instruments in any configuration.
