Hey guys, I need some help picking the right peep sight for my KDE. I ordered the Williams WGRS peep sight but I am wondering if I should have gotten the Williams FP. It would appear that the WGRS would be easier to install but the FP seem like it has more capabilities for wind and distance adjustments but harder to install. Another difference seems to be where they mount on the gun. The WGRS looks like it mounts in place of the rear sight where as the FP mounts in the rear scope holes giving you more distance between the peep sight and the front sight. So with that said what is the consensus on which one is better and why? Thanks in advance for the advice.
