Newest Version 4 Zev Tech Stainless Steel Skeletonized Striker. Extended tip eliminates light primer strikes for complete reliability even with hard primers. Lightened weight and skeletonized design completely changes trigger pull feel by reducing striker bounce and vibration. Trigger stacks up and "pops" cleanly. This striker is specifically designed to work with shortened pretravel trigger bars such as the ZT Fulcrum and ZT Standard but also works with factory trigger bar. Polished engagement surfaces eliminate trigger creep.
