The FP PWR Insert features a Fluoro Polymer Coated finish for enhanced performance. The process involves multiple cycles of baking and controlled cooling. The application is known as PTFE (Ni/PTFE) in which the end result is a hard, scratch resistant surface. This coating provides a slicker surface, resulting in a softer sound signature and smoother bore. The insert is available in the following sizes: .679, .681, .683, .685, .687, .689, .691, in a sophisticated gilded color. The CRBN FP Inserts build on the proven PWR™ System, with 7 optimized bore sizes and finished with laser-etched labeling. Each 8.5" insert is precision broached and micro-honed for the utmost accuracy. The PWR™ Insert's chamfered breech opening and stabilized collar assists untimely ball breaks in the barrel, making it the best insert system available. Compatible with any barrel that accepts PWR inserts, including the IC PWR™ Nano Barrel. PWR™ trademark is owned by Planet Eclipse Ltd.
