Goes to show how quickly things can get out of hand optic wise with a misaligned trunnion even at TIs spec. Aligning a basic / old school optic like a Vortex Crossfire, PSO's, POSPs, Russian red dots on a bent Type 81 in a worse case scenario can gobble up at least 70% of your windage adjustment. But then again lots of nicer optics have like 100 plus MOA of adjustment too.
