The Ade Advanced Optics Crusader is a red dot style reflex sight designed to provide users with an easy to use, easy to see reticle for rapid, up close engagements. The Crusader uses a square window design that is hooded and heavily protected from debris and dust. The Crusader offers a quick-detach option that fits any standard 1-inch Picatinny or weaver scope rail. The optic also has unlimited eye relief so it can be mounted far forward on rifles that traditionally don’t offer traditional scope options, like the AK 47.
The Crusader has four different reticles, and each reticle is available in either red or green. The reticles are a single dot, a crosshair, a crosshair with circle, and a skull. The skull is an odd option, but it is large, and acts as a simple circular reticle. The device has five different brightness settings, all designed for daylight shooting. The Crusader offers a wide and crystal clear viewing window that gives the user a large field of view.
The Crusader utilizes a solid aluminum body and mimics Eotech’s controls, which means the controls are well placed and very easy to access. Reticle color can be changed on the fly to deal with a particular environment. The Crusader uses a built in rechargeable battery and has a charging indicator. The Crusader can be used with both magnifiers and night vision devices. For a great price, the Crusader offers a lot of versatility, and an excellent array of options.

The Bushnell TRS 25 changed the optic’s game. A lot of people fail to realize that the Bushnell TRS 25 changed how affordable optics functioned and how much they have to cost. The TRS 25 hit the scene and became an immediate success. This is a compact red dot with a 25 mm objective lens.

The TRS 25 spots a 3 MOA optic reticle that is perfect for rifles and shotguns. Its small enough to be precise for moderate range shots, but large enough to quickly catch the eye. The red dot itself is compact and can mount to almost anything, including small pistol caliber carbines. The TRS 25 features a high contrast Amber tint to help with low light shooting and to reduce glare. It really livens up the world around and lets you clearly see and engage your targets.

The Best Red Dot under $100: CQB
Close quarters optics are extremely popular, and their prices range greatly between less than twenty dollars all the way up to more than a thousand (like Eotechs and Aimpoints). At under a hundred, the optics here may not be be built to military specs but unless you are a SEAL knocking on doors in the Peshawar, they will serve you very well. Good luck!
