The NcStar VMKMBA KeyMod swivel stud and bipod adapter bridges the gap between modern modular rail systems and traditional sling attachment points. Built from hardcoat anodized aluminum, this compact adapter lets you mount a KeyMod-compatible bipod or accessory directly to a standard rifle sling stud, giving you the flexibility to run contemporary gear on firearms that use classic attachment methods—or vice versa. It's the kind of no-fuss solution that shooters, hunters, and range competitors appreciate when they need to adapt equipment without permanent modifications.
KeyMod has carved out a solid following among AR and modern sporting rifle builders, but not every firearm or mounting surface is designed around that standard. The VMKMBA solves that compatibility puzzle. The hardcoat anodized finish resists wear and corrosion, so the adapter holds up under field use, whether you're shooting prone at a match, glassing from a blind, or breaking in a new rifle at the range. Weighing almost nothing and taking up minimal space, it's an easy add to your parts bin.
This is one of those accessories that seems simple until you need it—then you realize how much versatility it adds to your setup. If your bipod, rail accessory, or other gear uses KeyMod mounting and your rifle or chassis has a sling stud, this adapter makes them work together without compromising either.

Yes. The VMKMBA is designed to mount KeyMod accessories to a standard rifle sling stud, so a KeyMod bipod or rail accessory will attach to the KeyMod side of the adapter, and the swivel stud portion fastens to your rifle's sling attachment point.
Any rifle or chassis with a standard sling stud can use this adapter. It's not caliber- or action-specific; compatibility depends only on having a sling stud mounting point.
No. Hardcoat anodizing is a finish applied to aluminum for durability and corrosion resistance. It does not affect the mechanical fit or how the adapter functions—it simply makes the aluminum tougher and longer-lasting in the field.
