Bore size determines airflow and, consequently, FPS and efficiency in hpa nozzle setups. The ideal bore size depends on your desired power output and efficiency; larger bores generally allow for higher airflow, potentially increasing FPS and making it easier to run at lower PSI for efficiency. For example, the Amped Custom Fusion Engine Plus Nozzle for M4 offers a 20% larger bore than standard nozzles, resulting in higher output and the ability to use the nozzle for DMR or sniper setups. Having a variety of bore sizes available means you can tailor your build for either high power or efficient, consistent performance.
