Good tool as long as front post doesn't bottom out.
Can't get the tool between the ears on my sight. Looks like I'm not the only person with that problem.
Tool doesn't fit into the front sight indentations very well....might be the sight itself, or the tool. Not sure which is the problem. It's easier and faster to adjust the front sight with a loose round.
I bought the diamondhead backup sights and found out that it was not possible to adjust the front sights without this tool
