sti adjustable rear sight

The STI adjustable rear sight is a replacement part for STI pistols that have an LPA/TRT size dovetail cut (60-degree X 0.375).  This sight has a one-piece blade with an adjustable tunnel. 

You will find that many guns with an adjustable rear sight use a BoMar style dovetail.  However, in the last few years STI has switched to using LPA/TRT sights for their adjustable rear sights.  To determine which sight is on your gun, look at the elevation screw on the sight.  On Bomar style sights, the elevation screw goes into the slide behind the dovetail.  On the LPA/TRT sight, this screw goes into dovetail.  If the elevation screw lines up with the dovetail then it is an LPA.

Brazos Recommends an Alternative:  Check out the STI compatible Brazos Top Notch adjustable rear sight -- a better choice at a better price!  Also available with the BoMar dovetail.
