🔍 Why Choose a Red Dot for Your AR-15?

Red dot sights offer the ideal balance between speed and simplicity:

• No magnification – perfect for close to mid-range use
• Unlimited eye relief – shoot with both eyes open
• Parallax-free – the dot stays on target, even if your head moves
• Lightweight & compact – no unnecessary bulk
• Perfect for co-witness setups with your iron sights

Many models are also night vision compatible, solar powered, and offer motion-sensing wake functions, making them ideal for tactical and all-weather scenarios.

🔧 Find the Best Red Dot for Your Build

Every shooter has different needs — here's how to choose the right sight:

• CQB & home defense: Go for a 2–4 MOA red dot or reflex sight with fast adjustment dials and shake-awake features
• Mid-range builds: Pair a red dot with a 3x magnifier for versatility
• Tactical rifles: Look for rugged optics like the Aimpoint PRO or Holosun 515, built to survive harsh use
• Budget builds: Great performance is still possible with optics from Vortex SPARC, Primary Arms, or Bushnell CQTS
