NcSTAR AR-15 Lower Receiver Vise Block, Blue Anodized Aluminum

Description

Building or servicing an AR lower is a whole lot easier when the receiver isn't fighting you. The NcSTAR AR-15 Lower Receiver Vise Block clamps into any standard bench vise and gives your MIL-Spec lower a rock-solid home while you work. A pistol grip bolt threads right into the grip screw hole to lock the receiver down, so you can install parts, swap components, or run maintenance without the whole thing spinning around on you.

What the NcSTAR Vise Block Handles

Made from anodized blue aluminum, this block is light enough to toss in a range bag but sturdy enough to take real torque. The finish resists scratches and corrosion, which matters when the tool lives on a workbench next to solvents and oils. The newer version of this vise block also plays nice with MIL-Spec AR-10 lowers, so it earns its keep across more than one platform if you run both.

Getting the Buffer Tube On Straight

The part that really sets this apart is the removable buffer tube support ring, which mounts to the block with three thumb screws. When you're threading on a carbine buffer tube, the ring holds it square and plumb to the receiver. That means the castle nut tightens down clean without cocking the tube off-axis, and it takes pressure off the back plate notch so you're not chewing up your receiver extension threads. Anyone who has tried to line up a buffer tube by feel alone knows how much of a headache this little ring saves.

Simple Enough for a First Build

Using it is about as basic as gunsmithing tools get. Secure the pistol grip bolt into the lower, drop the block in your vise, and optionally add the support ring when you're working the buffer tube end. It's the kind of tool that pays for itself the first time you build a lower on the kitchen table and don't have three extra hands to keep everything lined up.
