Consistency is paramount for every dedicated hunter, and these Ravin .001 Premium Match-Grade Lighted Arrows deliver ultimate precision. Boasting an exceptional straightness tolerance of just .001", these arrows ensure razor-sharp accuracy. Engineered for seamless performance, they are precisely weighted to match Ravin's standard non-lighted arrows, even with the added lighted nock, guaranteeing identical, predictable flight characteristics. The ultra-bright lighted nock dramatically improves visibility, making quick and effortless arrow location a consistent reality for hunters and target shooters. Please note: These arrows are designed for use in all Ravin models EXCEPT the R500 Series Crossbows.
