Parallax Sidewheels are specially designed for the Big Nikko or Sightron S3, featuring a 42mm parallax knob but can be adjusted to fit any other size parallax knobs upon request. With a generous 130mm diameter, these sidewheels enable larger range mark gaps than standard ones. Choose from a variety of vibrant colors, and if you can’t find your preferred shade, contact us, and we’ll likely have it in stock. Perfectly enhance your shooting experience with Parallax Sidewheels!
This model can be adjusted to suit other diameter parallax knobs.
