    • 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

    • 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.

    • Works well for the price
It does what its supposed to for my purposes, I will be using it on an old 22 plinker that the iron sights dont hold zero due to damage. I am sure it can also be used on airsoft or other small calibers. For the price it works well, the red and green dots are clearly visible in low to medium light environment. ... show more

    • Good feel
Just got this and attached it, went on pretty good and functions as it said it will. Haven’t had a chance to sight it in yet but it feels sturdy. Will update after using a few times.
