## Description

The 3rd Generation (Mk III) Universal Field Sight Pusher is the do-it-all solution for the home gunsmith. Not it only changes the dovetail sights of your guns (both front and rear), it also compacts as to fit a thin pocket of your range bag or a corner of your gun case. This helps you to always be ready to adjust the sights of your guns whenever needed at the range without requiring you to disassemble their slide. The hardened alloy steel Pushing Heads allows the tool to fit different sight profiles and move them efficiently. The Glock 42/43 tool set includes the "Universal" and both "Glock Standard" and "Glock 42/43" versions as to also fit all Glock factory style sights. The Adapters allow the tool to be attached to the slide without causing mars, while also increasing it's effectiveness. The tool set includes the "Universal" adapters which makes the tool function on flat sided (or square shaped) slides at the rear and most slide designs at front. Features, versatility, durability, quality and value.
