    FRONT SIGHT

    Simple install for me on MK IV Target model using original mounting screw. I appreciate the inclusion of wrenches.No issues with alignment. Green fiber optic on the sight that I received does not seem bright enough (looks faded) for my aging eyes but an easy fix. I recommend this upgrade.

    Could not have been easier. Instructions clear and took about two minutes to change. Product appears of good quality and made a huge difference in visualization of the front sight. Just get it!!

    simple, easy quick install to mk iv lite. Comes with 2 allen keys for removal of oem screw and install of TKs screw. Factory screw was EXTREMELY tight, twisted the allen key supplied by TK lol

    Way, way better than a drop of orange paint on stock front sight. Sight really stands out against steel challenge targets. Easy to install. Good stuff!!

    Fiber Optic Front Sight

    Posted by Dave T on 6th Mar 2025

    An easy to install (it took me about 10 minutes) sight replaces the standard sight, and it makes a significant improvement in acquiring the front sight. Installation requires removing a single screw, replacing the sight, and re-installing that single screw. Couldn’t be much easier than that. The result is a front sight that’s much easier to acquire, and this improves aiming accuracy. This is a super affordable, easy to install product that results in a significant upgrade to the factory stock front sight. After the Halo Ring, this should be the next upgrade to a Ruger 22/45 Lite pistol.
