MAGPUL | Dynamics Precision Rifle Data Book 2.0

The Magpul Dynamics Precision Rifle Data Book uses a simplified density altitude-based, color-coded chart to record your rifles' data across a wide spectrum of shooting conditions. Using a rugged, all weather material that can be written on using map pens, pencils, and non-permanent markers, this data book was designed to perform in austere conditions. Recorded data can also be erased with alcohol based substances, returning the material to its original state.
