text: These allow the high rates of fire seen in full electropneumatic designs at a very low cost compared to higher-level markers; however they typically have both the higher recoil of poppets (even worse, typically, as the designs use a traditional high-mass hammer driven forward by a spring) and relatively low gas efficiency due to a single operating pressure.
