- Optic format: It is described as compatible with RMR, T1 and T2 red dot sight formats. Confirm the exact sight pattern you intend to fit.

Compatibility, Size and Fit
Compatibility centres on two points: the 20 mm Picatinny rail and the stated red dot sight formats. Check both the rail and the sight pattern before choosing an offer, since a mount can only work correctly when the fitting points match.
Before You Decide
