Bisley HETO38C Two-Piece Extended High Scope Mounts
The Bisley HETO38C is a two-piece, extended (reach-forward) high scope mount set designed for 30mm tube scopes. It fits rifles with a 9.5–11.5mm (3/8in / 11mm) dovetail rail.
Each mount features a four-bolt top ring and two-bolt base for a secure clamp. The set is suitable for scopes with an objective lens up to 56mm in diameter.
The extended front mount steps the scope forward, providing approximately 25mm more eye relief than a standard two-piece mount. This is ideal for rifles where a conventional mount places the scope too far back.
Mount height is 21mm. A removable arrestor pin is included to help lock the base against recoil.

Installed the mounts on my rifle and noticed a significant improvement in eye relief. The scope sits much more naturally in the eye, which reduces strain during long shooting sessions. The clamp is solid and the arrestor pin works well to prevent movement during recoil.

The extended design gives better positioning for my 30mm scope. It’s easier to align the sight with the target. The mount is secure and the height is just right for my rifle setup.

Fits perfectly on my dovetail rail. The four-bolt top ring provides excellent stability. I appreciate the included arrestor pin—it helps keep the base locked during firing.
