RST RearSightTool®
Designed to be always with you

RST RearSightTool® Gen 3 Universal Field Sight Pusher

The 3rd generation of RST RearSightTool® Universal Field Sight Pushers introduce the capability of performing sight installations while maintaining the trademark always range ready philosophy. In addition, the Gen 3 UFSP also introduces the Quick Change Adapters which allow for direct use of the tool to the slide and the configuration of the tool to fit guns previously not compatible. Overall, the Gen 3 Universal Field Sight Pusher is the best sight tool for the home gunsmith where one tool has to do it all.

Quickly change the sights of your guns

Due to the very open design, tool set up to the slide is quick. In addition changing configurations from sight removals to installations don't require the overall disassembly of the tool due to the Spacer Block and Adapters being removable with the tool assembled.

Always ready for the range

The Universal Field Sight Pusher is designed to be as portable as possible so it can be stored in your range bag or gun case so its always at hand. This is achieved by allowing the tool to be dissasembled into a small and tight package.

No handgun disassembly required

Our patent pending design allows for fast and precise rear sight adjustments without the need to disassemble your semi-automatic handgun.  The RST RearSightTool® Universal Field Sight Pusher won't make you lose precious time on the range.

 No extra tools required

Due to the knobs, our tools don't require spare wrenches, pliers or Allen keys to work.

Safe for your sights

The Pushing Heads system allows for much more efficient and precise sight adjustments. Also, thanks to the sight-specific designs, no damage to the sight is made during the adjustment process. Currently pushing heads are offered for the following types of sights:

  • Universal: For sights with flat and vertical sides.
  • Glock Standard: For Glock sights with angled sides.
  • Glock 42/43: For Glock 42/43 sights with angled sides.

Safe for your slide

The hard polymer adapters avoid scratches and increase the effectiveness of the tool. Different designs allow the tool to function over model specific designs.

Tall sights compatible

We have designed our devices bearing in mind users with handguns equipped with suppressor ready sights. Our tool will work with these sights without the need of spare adapters or accessories.

No more figuring out

Our tools features a quick reference on one of the plates to aid you in using it. Don't waste more time figuring out how the adjustment of the sights work, just give a fast look to the diagram and use it how you need it.
