Solar-powered and built for battle, the Holosun HS503CU offers a crisp 2 MOA dot or 65 MOA circle for lightning-fast target acquisition.


Tough, reliable, and fast—this Gen 2 red dot is ready for your rifle.
Whether you’re clearing corners, hunting across open terrain, or shooting long-range, tactical rifle scopes and red dots cover every scenario. This combined category gives you both speed and precision—without compromise.
When fractions of a second matter, red dots dominate. Both-eyes-open shooting ensures situational awareness while delivering lightning-fast target acquisition. Compact, rugged, and reliable, red dots excel in home defense, competition, and tactical training.
For long shots, rifle scopes step up. Variable magnification lets you zoom in for distant targets or pull back for mid-range engagement. Clear glass, illuminated reticles, and rugged construction mean these optics hold zero under stress and adapt to changing light.
Pair a red dot with a magnifier, or mount a scope on your AR platform to cover all ranges. Many professionals carry both—because real-world situations don’t limit themselves to one distance.
At FKTG Tactical, we stock trusted optics from Holosun, Sig Sauer, Primary Arms, and Trijicon. Every sight is tested tough and built for shooters who demand more. From rapid CQB response to precision long-range fire, we’ve got you covered.
