The Trijicon RMRcc 6.5 MOA is a Trijicon RMRcc optic. Here is how it clamps a 20 mm airsoft RIS rail and the one thing to check on a clone rail.

Direct fitThe Trijicon RMRcc 6.5 MOA runs on a 20 mm RIS or RIS II airsoft rail through its RMRcc-footprint Picatinny mount, exactly as on a live-fire Picatinny rail. On a good replica rail it clamps square; on a cheap clone rail, seat it dry first and confirm it locks, because clone rails can sit out of Picatinny spec.

A 20 mm RIS or RIS II airsoft rail is built to the Picatinny pattern, so the RMRcc-footprint Picatinny mount that carries the Trijicon RMRcc 6.5 MOA on a live-fire rail clamps the replica rail the same way. The footprint choice does not change: it is still a Trijicon RMRcc optic on a Trijicon RMRcc mount.

The variable on airsoft is the rail, not the sight. A quality RIS or RIS II rail holds Picatinny slot width and pitch, but a budget clone rail can run slightly narrow or wide. Seat the mount dry, check the Trijicon RMRcc 6.5 MOA sits square, and confirm the clamp locks before a skirmish so recoil-free cycling does not shake it loose.
