Unlike other vise blocks on the market, all of which are made from a single piece of polymer or metal, the Real Avid Vise Block features an adjustment handle that changes the tension level produced by the block inside of the AR magazine well. The adjustment works through a threaded post connected to a wedge that can be adjusted throughout the length of the vise block, providing a custom fit for nearly any AR magazine well design out there.
The Real Avid Smart-Fit AR-15 Vise Block enhances the ability of users to work on their AR while doing precision cleaning or adding small, easily lost components in the process of an upgrade or components swap. One-size-fits-all blocks often allow mounted ARs to wobble, leading to potential frustration during maintenance. The solid, secure fit of the Smart-Fit block ensures that users can do precision work with small components without worrying about their rifle moving out of place.
One of the other benefits of the tight-fitting block is the ability to hang the AR-15 upside-down from a bench vise without worrying about the unit coming loose. This enables users to perform trouble-free work on the underside of the AR-15 lower receiver, such as swapping out pistol grips. The tool also includes Real Avid's unique Pivot Lock, which keeps the upper receiver angled in a convenient position for cleaning or removing internal components without letting the barreled assembly swing forward to receive potential dings or damage from the side of a user's work bench.
Each Real Avid Smart-Fit AR-15 Vise Block retails at a suggested price of $29.99.
