No, you aren’t looking at a mistake. This was done intentionally.

According to MBX, this offset will make a PCC shooter faster since they do not need to waste time getting a proper cheek weld to get their sight picture. In theory that works for strong handed shooting only. But once you need to lean hard left and shoot from your weak shoulder around a barricade things get tricky. You could roll the gun to get the optic closer to your left eye but now you shift POI.

I know speed is critical in USPSA but the compromise seems too great for the modicum of speed you might gain from this. The good thing is it only costs $25 for the off set plate.

Maybe they should make a wider plate and put two cmores on the gun.
