    • Best red/green dot I’ve own.
The 551 Tactical Red Green Dot Holographic Sight is an absolute game-changer for airsoft tournaments! This optic fits perfectly on my 20mm rail mount and provides crystal-clear targeting with both red and green dot options. The reflex sight allows for quick target acquisition, which is crucial in fast-paced airsoft scenarios. It holds zero perfectly, even after intense gameplay, and the durable build is perfect for outdoor use. Whether you’re in close-quarters combat or engaging from a distance, this sight gives you a tactical edge, improving accuracy and speed in the field. If you’re serious about airsoft and looking to dominate your next tournament, this sight is a must-have accessory! ... show more

    • There's a reason why it is $1,000 cheaper
It's exactly what you would expect for a clone of an actual unit. I wouldn't trust it for anything other than airsoft or for a visual display but the metal it's made out of actually feels pretty good doesn't hold zero but again I was expecting that

    • Very nice site
This is a very bright little site that is easy to use. It is very stable on top of the real its quality, and it maintains a very good accuracy after being dialed in. Say this is just as good as any of its namebrand competitors at a fraction of the price.

Great for air-soft. Quality isn’t good enough for an actual weapon.
