Simisdim details the evolution of his MWS, which originally featured a stock buffer tube, a DE bolt with an Angry Gun nozzle set, an original barrel, a Maple Leaf yellow 60° hop rubber, and a Jaeger Precision Titan nub. After a nozzle crack impacted accuracy, he replaced it with a Jaeger Precision NPAS—requiring some filing to fit—alongside a flamingo pink hot rubber and a Waldo Dynamics nozzle spring, addressing battery return issues. His current setup includes a DE bolt with the Jaeger Precision NPAS, a flamingo pink hot rubber, the same hop nub, and a 140% Waldo Dynamic spring, complemented by external upgrades like a CTR stock and an AirCro sling.
