HIVIZ Fiber Optic Front Sight for Glock (Excludes 42, 43, 43X, 48, MOS) - Green, Red, White

The Hi-Viz fiber optic front sight for Glock is a rugged upgrade designed to get your sight picture fast, even when speed counts. This .315" high front sight works with Gen1 through Gen4 Glock pistols (except G42, G43, G43X, G48, and MOS models), making it a natural fit for shooters running standard Glock slides who want to brighten their sight acquisition without going full optics. The interchangeable fiber optic inserts—green, red, and black—let you dial in the sight picture that works best for your lighting conditions and shooting style, whether you're at the range, hunting, or training for personal defense.

Hi-Viz engineered this sight with a sturdy steel body and satin black finish to withstand the wear of serious use. The three included inserts give you flexibility: the bright green and red fiber optics gather ambient light and stand out in daylight and indoor ranges, while the opaque black insert delivers a traditional target sight picture when you prefer iron-sight fundamentals. Swapping inserts takes seconds, so you can adapt to different scenarios without tools or downtime.

This front sight is purpose-built to pair with Hi-Viz's GLAD211 adjustable target rear sight, but it also works in any setup where a high front sight is needed. If you're looking to add speed and visibility to your carry or competition Glock without committing to a red dot, this is a proven, affordable way to modernize your sight picture.
