Maintaining the heavy recoil impulse of the VFC SCAR-H MK17 gas blowback rifle means you must keep the internal trigger group operating under very strict tolerances. Over time, the constant violent cycling of the bolt carrier group will naturally fatigue the trigger mechanism, which often leads to sluggish resets or frustrating failure-to-fire issues out on the field. To fix this, the VFC sear spring, known as part number 08-16, serves as an original factory-spec replacement designed to restore that precise mechanical tension. Crafted from heat-treated, high-tension spring steel for an incredibly long cycle life, this tiny micro-component is absolutely essential for securing proper sear engagement. By dropping in this single piece of spring steel, you guarantee highly consistent trigger breaks and a reliable semi-automatic reset, keeping your primary gas blowback platform running flawlessly under the most stressful tactical conditions. The package includes one exact-fit factory sear spring ready for immediate installation.
