The Bisley Two Piece High 30mm Mounts for 15mm CZ527/Fox are scope rings made for securely attaching optics to rifles that use a 15mm dovetail rail system. This type of rail is narrower than the more common 11mm or Picatinny systems, so these mounts are specifically engineered to match that sizing and ensure a tight, stable fit.

The mounts are split into two separate rings rather than being joined on a single base. This allows more flexibility in positioning the scope along the rifle’s rail, which helps with achieving correct eye relief and comfortable shooting posture. Because each ring is independent, it also allows better adjustment when fitting different scope lengths or balancing the rifle setup.

They are designed for scopes with a 30mm tube diameter, which is a standard size for modern hunting and precision optics. The “high” height specification means the scope sits higher above the barrel, giving clearance for larger objective lenses without touching the barrel or affecting bolt operation. This is especially useful for scopes with larger front lenses often used in low-light hunting conditions.

The mounts are built to provide a firm and stable grip on the rail, helping maintain zero even under recoil. They are typically tightened using clamp screws, and many versions include recoil resistance features to prevent movement during repeated firing. However, because they are designed for a specific rail type, correct compatibility is essential before fitting.

Overall, they are a practical mounting solution for shooters using CZ527 or Fox rifles who need a secure, elevated scope position with reliable stability for field or hunting use.
