BROWNELLS SIGHT WRENCH FOR AR-15

The Brownells Sight Wrench for AR-15 is a precision-machined adjustment tool designed to simplify front and rear sight adjustments on AR-15, M16, and related rifle platforms. Constructed from tough stressproof steel, this specialized wrench provides secure engagement with sight detents for precise zeroing and repeatable sight corrections without damaging the sight assembly.

Square-profile engagement fingers grip sight notches firmly to help prevent slipping during adjustment, while the deeply drilled body accommodates both standard and tall front sight posts. The hex-shaped body provides a comfortable grip for positive control and helps prevent the tool from rolling off the workbench.

Available in A1, A2, and combination A1/A2 configurations, the Sight Wrench allows armorers, competitors, and firearm enthusiasts to make quick and accurate sight adjustments both at the bench and on the range.

Works when used on the right sight.

I gave a scathing review of this tool below, but have learned a little more about it since and would like to revise my statement. I can't edit that review, so I'm adding another one. My front sight is a Samson and the fit of the post seems a bit tight. Moreover, I was adding a Trijicon tritium post and it's built a little differently than the standard one. The part of the post that this tool turns is taller on the Trijocon than the standard one and the prongs on the tool aren't long enough to depress the pin far enough to let the post turn, so this tool will not work on that sight. It will probably work okay on a standard post, as long as it's not too tight.
