This operating system for the top half of a popular modern sporting rifle uses a short-stroke gas piston system to cycle the action, as opposed to the direct impingement system found in the original design. A metal rod, or piston, is affixed to the bolt carrier group and sits within a gas cylinder. When the rifle is fired, expanding propellant gasses drive the piston rearward, imparting momentum to the bolt carrier group to initiate the reloading cycle.
This design is often favored for its potential advantages in reliability and maintenance. By containing the hot, expanding gases within the piston system, less carbon fouling and heat are transferred to the bolt carrier group, theoretically reducing wear and improving function in adverse conditions. This mechanism can also lead to a smoother recoil impulse, potentially enhancing accuracy. The development and implementation of this operating system reflect an ongoing evolution in firearms technology, seeking to improve upon established designs.
Further exploration will delve into the specific advantages and disadvantages of this operating system compared to direct impingement, discuss various manufacturers and models available on the market, and analyze the impact of this technology on practical applications.
1. Reduced Fouling
