Lower Receiver Block That Adjusts For A Rock Solid Fit. 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, 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. When you think about it, this brilliant design makes other blocks seem obsolete.

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.

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.
