Overview
Built for shooters who want added target detail without giving up fast transitions, this 5x magnifier pairs a quick-transition mount with tool-free vertical and horizontal adjustments for straightforward setup. The adjustable diopter and wide field of view support a clear sight picture, while the compact form factor keeps the package manageable on the rifle. It is compatible with all EOTECH HWSA models and mounts to a 1" Weaver or MIL-STD-1913 rail, making it a practical option for precision-focused use. The STS mount adds convenience, though the setup is still centered on magnified observation rather than a full optic replacement.

Considerations & Trade-offs
- Fixed 5x magnification means it is built for one magnification level rather than variable zoom flexibility.
- The STS mount adds weight; the unit is 12.8 oz with the mounting system installed.
- At 3.9" x 2.3" x 3.3", it adds noticeable size to the optic setup and may affect balance or rail space.
- Compatibility is listed for EOTECH HWSA models and 1" Weaver or MIL-STD-1913 rail mounting, so fit should be confirmed before purchase.
