NcStar MAD38PS 3.75" Black Aluminum Dovetail to Picatinny/Weaver Adapter

- Black
- Model:
- 3/8 Dovetail to Picatinny Adapter
- Material:
- Aluminum
The NCStar MAD38PS 3.75" dovetail to Picatinny adapter solves a common optics and accessory mounting problem: getting modern rail-mounted gear onto vintage or legacy firearms built around dovetail grooves. This black aluminum adapter bridges that gap, letting you mount scopes, red dots, lights, and other Picatinny/Weaver accessories on 3/8" dovetail-equipped rifles and shotguns without permanent modifications.
Built from aluminum and finished in black anodizing, the MAD38PS handles the mechanical demands of firearm use—it's robust enough for hunting, tactical training, and range work. The adapter works bidirectionally: dovetail on one end accepts your gun's groove, while the opposite end features standard Picatinny rail for your choice of optics or accessories. That flexibility makes it a practical add-on for gunsmiths, hunters upgrading older rifles, or anyone reviving a firearm that predates today's rail standard.
Installation is straightforward—no gunsmithing required. The dovetail interface is mechanical (friction-fit with set screws for security), so you can adapt and swap accessories quickly if your needs change. It's the kind of accessory that earns its place in your range bag or truck bed when you're working with mixed-era firearms or inherited rifles.
