This is an unique swivel Picatinny mount adapter. You'll need to purchase two of these mounts, then fasten the two mounts together with a #8-32x3/4" screw and nut. Tighten the screw and nut to the desired tightness. Then use Loctite to fix the screw and nut into a hinge. The adapter can be fastened to Picatinny rails or Weaver rails using #6-32x1-1/4" screws and nuts. The screws and nuts are not included, but can be acquired at your local hardware store (Home Depot, Lowes, etc.).
his swivel Picatinny mount adapter provides 180 degrees rotation. Why would you want to do that? Perhaps you want to be able to swivel your mounted SmartPhone... We'll leave that up to your imagination.
Airsoft equipment used for illustration of this swivel Picatinny mount adapter are not included.
