Ncstar Vice Block Tool For Glock

Working on your Glock's slide doesn't require a gunsmith's bench—the NCStar Vice Block Tool for Glock gives you a safe, repeatable way to secure your slide in a standard workbench vise. This anodized aluminum block slides onto your slide's frame rail grooves and clamps securely between vise jaws, holding the slide stable while you perform maintenance, install sights, or do other detail work. It's designed to protect your slide from marring and distribute clamping pressure evenly, so you can work without worrying about damaging your firearm.

The block fits most Glock models built on Standard, Compact, and Subcompact frames across common calibers—9mm, .40 S&W, .45 ACP, 10mm, .357 SIG, and .45 GAP. It won't work with the slimline designs (Models 42, 43, 43X, and 48), so verify your model before ordering. Setup is straightforward: insert the block onto your slide's rail grooves, clamp it in your vise, and tighten gradually. The key is not to overtighten—firm pressure is all you need.

If you reload, upgrade sights, or like to keep your carry gun running smooth, this tool makes hands-on maintenance easier and more consistent. It's a compact, affordable way to add workbench capability without dedicated gunsmithing equipment.
