Description
The Real Avid Smart-Torq Fixed Limiter & X3 Driver Kit combines six pre-set torque limiters with a 3-in-1 ratcheting driver and a 12-piece bit set for torque-critical gunsmithing tasks like scope mounting, rail installation, and action screw tightening.
The six fixed limiters are set at 15, 20, 25, 30, 45, and 65 in-lb — the most common torque values for optic rings, mount bases, and action screws. Each limiter uses a click-style overload clutch rated to ±5% accuracy. You thread the limiter between the driver and the bit, tighten until you feel and hear the click, and stop. Unlike adjustable torque wrenches, fixed limiters don’t need to be dialed back to zero for storage, and there’s no risk of accidentally leaving the tool set to the wrong value between tasks.
The X3 Driver is a 1/4″ hex drive tool that converts between three configurations: a 72-tooth ratcheting driver for precise work in tight spaces, a T-handle for added leverage, and a standard inline screwdriver for general use. The non-slip grip is comfortable for extended use.
The 12-piece bit set includes six hex bits, four Torx bits, one #2 Phillips, and one 5mm flat bit. A 4-inch extension handles long-reach fasteners like grip screws and buttstock bolts. A 1/4″ hex-to-1/4″ square adapter and 1/2″ socket round out the kit. All bits are standard 1/4″ hex, so the kit works with any aftermarket bits you already own.
Everything stores in a hard-sided, stackable case. Additional fixed limiters are sold individually in values from 7 to 100 in-lb if your work requires settings outside the six included values.
