Smart-Fit® Vise Blocks: Precision Tools for Glock/AR9, AR15 and AR10 Maintenance

The Smart-Fit® Vise Block System is a precision-engineered line of firearm maintenance tools developed by Real Avid to provide secure, adjustable support for a wide range of modern sporting rifles and pistols. Designed specifically for AR9, AR15 and AR10 platforms, each Smart-Fit Vise Block delivers stable, non-wobbling performance during firearm disassembly, maintenance, cleaning, inspection and assembly procedures. These vise blocks feature a patented expandable design that eliminates movement inside the magazine well, allowing for consistent alignment, safer operation and improved working efficiency on the bench. 

Each vise block in the Smart-Fit family is built to solve a common problem experienced by gunsmiths, armorers and firearm enthusiasts—the instability and poor fit of traditional vise blocks. Rather than relying on a static, one-size-fits-most block, Smart-Fit tools employ an expanding mechanism activated by a twist-adjustment handle or knob. This creates a tight, form-fitting hold inside the magwell of the firearm’s lower receiver, securing the firearm to the bench vise without damage to the receiver or risk of unwanted movement. The result is a highly stable, firearm-specific vise block system designed to withstand repeated use under demanding conditions.
