VICTOR COMPANY USA, INC. RPG CHASSIS SYSTEM W/HR1 13" HANDGUARD FOR RUGER 10/22® The RPG Chassis System with the HR113” Handguard is built to give the 10/22® platform the same control, balance, and precision feel as a modern AR-15 carbine. The chassis uses a rigid one-piece receiver block to lock the action into place, eliminating flex and maintaining a consistent point of impact. The 13” HR1 Handguard brings AR-15 ergonomics to a rimfire trainer—lightweight, stable, and fast to handle—with a built-in ARCA section up front for tripod and bipod integration. M-LOK slots along the handguard give you full accessory flexibility, while the slim profile keeps transitions smooth and predictable. Designed for shooters who want a compact, maneuverable chassis with centerfire handling and rimfire economics, the HR1 configuration hits the sweet spot between stability, weight, and speed.
