Reply To: BKL high or FX No Limit?
FX no-limit scope rings allow you to keep your scope optically centered for the brightest image. First, optically center your scope. Then do a “rough zero” by adjusting the no-limit mounts. Once your rough zero is found, tighten down the mounts. Then do a final zero with your turrets. This results in a final zero that is very close to the scope’s optical center and the best light transmission (brightest image). Keeping a scope close to its optical center optimizes the amount of light that the scope can gather in. Using regular (non-adjustable) rings forces you to zero your scope with the turrets only, thus resulting in the scope being dialed outside its optical center and less light transmission (darker image). With airguns with barrel droop, no-limit mounts can make a dramatic improvement in your scope’s ability to transmit light.
