On a \u003cstrong\u003eforced reset trigger\u003c\/strong\u003e or Super Safety build where you're cycling at significantly higher rates of fire, that rattle compounds with every cycle, the tube heats up faster, and spring fatigue comes earlier.\u003c\/p\u003e\n  \u003cp\u003eThe SMB Gen3 eliminates that entirely. The polymer guide rod keeps the spring centered and off the tube wall throughout the entire cycling stroke — forward and rearward.
