AR-15 Lower Receiver Vice Block
The AIM Sports AR-15 Lower Receiver Vise Block is a polymer fixture that locks any MIL-Spec AR-15 lower into a standard bench vise for clean, stable work. It slides into the magazine well from the top or bottom and is captured by the factory magazine catch, keeping the receiver rigid without crushing or marring the aluminum. The solvent-resistant polymer body holds up to CLP, bore cleaners, and shop chemicals, making it equally at home during routine cleaning or full builds. At 4.9 inches long and just over 4 ounces, it earns its spot in any AR armorer's kit — whether you're swapping triggers, torquing a buffer tube, or assembling a fresh lower.

Features
- AR-15 Magwell Fit — Inserts directly into the magazine housing of any MIL-Spec AR-15 lower receiver from either the top or bottom for flexible workbench setup.
- Magazine Catch Lockup — Engages the factory magazine catch to lock the receiver firmly onto the block so it will not shift under torque.
- Solvent-Resistant Polymer — Molded from a tough polymer that shrugs off CLP, bore solvent, and common gunsmithing chemicals without softening or staining.
- Receiver-Safe Design — Will not crush, distort, mar, or scratch the receiver, protecting both forged and billet lowers during heavy work.
- Bench Vise Compatible — Clamps securely between standard bench vise jaws to keep the lower stable for cleaning, parts swaps, and full builds.
- Build & Service Ready — Holds the lower steady for installing trigger groups, buffer tubes, grips, selectors, and other small parts.
- Compact Footprint — 4.9" length and roughly 4.3 oz weight make it easy to store in a range bag or armorer's kit.
- Black Polymer Finish — Low-glare black finish hides shop wear and keeps the block looking clean over years of use.

Essential ToolI have built five AR lowers over the past couple years and for the first two I was trying to hold the receiver by hand or wedging it in a vise with rags wrapped around it like an idiot. This vise block changed everything. It slides right into the mag well and locks the lower in place so solidly that I can torque on castle nuts and buffer tube installations without anything shifting. The polymer material grips firmly without leaving a single mark on the finish which was my biggest concern. For the price this is one of those tools that you buy once and wonder how you ever worked without it. If you build or service AR lowers at home you need this on your bench.
