The Smart-Fit AR15 Vise Block is the last lower vise block you’ll ever need. The patent pending block expands to fit any.223 / 5.56mm AR15 magwell, eliminating loose, sloppy blocks for a rock-solid fit—perfect for cleaning, maintaining, or building your AR15.

Key Features & Design

Lower Receiver Block — Smart-Fit

• Patent pending block expands to fit any.223 / 5.56mm AR15 magwell, making loose, sloppy fitting blocks a thing of the past.
• Insert the block into the magazine well and simply rotate the adjustment handle to tighten the fit.
• This block can also be used with an inverted lower receiver to work on pistol grips or allow easy access to the underside of your AR15.
• For hassle-free cleaning, Real Avid included the AR15 Pivot Lock for hands-free access to the chamber and barrel.
• No more wobble and wiggle in your vise—adjustable fit for rock-solid support to clean, maintain, or build your AR15.
• Plus, the AR15 pivot lock securely holds the upper open for cleaning.

Upper Block — Lug-Lok

• Traditional clamp style upper blocks fit poorly and can exert enough inward pressure to damage the receiver when applying torque to a barrel nut or flash suppressor. That’s bad design.
• So, Real Avid designed an upper block that leverages the strongest part of the gun—the barrel lugs inside the star chamber. The Lug-Lok is precision machined and precisely fits into all Mil-Spec uppers.
• It mates perfectly with the barrel lugs, while allowing you to rotate the upper to be able to work on different sides.
• There are 2 vise pins that allow you to hold the upper at multiple working angles and prevent unwanted rotation during high torque application.
• The lock knob keeps Lug-Lok seated into the barrel lugs. The result—the safest, easiest and smartest way to lock down an AR15 upper into a bench vise.
