Otis Pro Plus Features The Otis Technology Pro Plus Punch Set includes five brass pin punches in the commonly needed sizes of 3/32 3/16 5/32 1/8 and 1/4 inch covering a wide range of firearm maintenance tasks. Brass construction allows these punches to move pins and components without scratching or marring sensitive firearm finishes an important advantage over steel punches. The hex-machined bodies improve grip and control during use while the chamfered striking surface reduces burring from repeated hammer strikes. Each punch measures 4 inches in length giving enough reach for comfortable handling during disassembly work. This set is well suited for installing or removing solid pins aligning internal parts and holding springs in place during firearm assembly and disassembly. A hard plastic storage case keeps all five punches organized and protected from damage between uses. Machined in the USA these punches are built to a standard that gunsmiths and hobbyists alike can rely on for precision work. Anyone maintaining their own firearms at home will find this 5-piece brass punch set a useful durable addition to their toolkit available at GrabAGun.
