Unfortunately, I could not find any information regarding a TA53 ACOG Thumb Screw being compatible with a Burris AR332 or a Primary Arms 2.5x32. I would recommend contacting both Burris and Primary Arms directly for more information.
Very well machined but with out the correct lock washer and spacer and no useful information on application to a ta 53.(Would not recommend to hold zero past 3 rounds )
Trijicon TA53 ACOG Thumb Screw is a part of the many parts offered by Trijicon. This part of Trijicon is a direct replacement for the thumbscrew included with the ACOG. With this part of Trijicon, you no longer have to worry about losing or breaking your lens because of the recoil. The Trijicon ACOG Thumbscrew is here to stay, because when you're using your ACOG and something goes awry with it, you can easily tighten it back in place. So, when you need to replace your Trijicon Thumbscrew, look no further than the Trijicon ACOG Thumbscrew. This part of Trijicon comes with a replacement ground glass so that you can get your Trijicon ACOG Thumbscrew back in shape.
