Beileshi Red Dot Sight, 4 MOA Compact Red Dot Gun Sight Rifle Scope with 1 inch Riser Mount

So far, so good. Used on full auto BB gun. Would work on firearm, but would opt for a 2 MOA or better IMO.

This is a great red dot optic for airsoft, brightness wise it is very easy to find the red dot and able to see it even in daylight, not so much on the lower setting but even on the 5th setting I could see it, also very nice that it comes with a raiser rail to have it higher up.

Excellent red dot and riser for the price! Although when attached and in testing, the optic was Sighted low and right from the warehouse/factory. Had to recalibrate.

Amazing, it holds zero and works great. It's light on the gun and very visible unless underneath sunlight. (The dot get's smaller). It lasted me a long time so, yeah I'd recommend.

Worked out so well I bought another one

Accurate, good battery life, lightweight and installs easy. Great sight quality and works well overall. Even comes with lens protectors!

I was impressed for the price I paid (19.99) at the quality, and the fact it comes with the riser in the price. However, my 5-star rating is simply based on for the value of what you get for the money. This is not a red dot I would trust on a powder-burner other than a low-end rimfire rifle. I ordered this for an airgun and have promptly ordered another once I received and tested. I compared to my TRS-25's and this one is slightly less bright on full power, but I was still able to see it enough in FULL sunlight. However, In bright light, the dot looks more like a 2MOA and I would choose the TRS-25 for hunting over this. The only thing else I can say is that I had bad experiences with cheap red dots until this one, and because of that I spent the extra for TRS-25's for airguns. If I had known this red dot existed, then I definitely would have saved the money and bought a handful of these. But there is no way I would use this on a centerfire rifle.EDIT: One thing I noticed after my initial review is that the glass on this one has a slight "green" tint to it vs the Bushnell TRS-25 which is completely clear when looking through it. HOWEVER, I do not consider that a deal breaker since this sight is so cheap for what you get. I would use this sight if you want to plink around, just don't put a 20 dollar sight on a 500 dollar gun and you'll be fine.EDIT#2: I bought a second unit and the quality control is lacking because the second unit is at least 50% dimmer than the first one I received. Therefore I have knocked it down 1 star and will update when I receive the replacement unit to see if this was a fluke, but if the brightness is hit and miss, then that could be a risk in buying vs. just getting a better sight. My Bushnells have been 100% consistent over multiple units. I will report back once I receive the now 3rd unit and see if it is any better. If not, I'm just going to be happy with the first one and send the other back for a refund.EDIT#3: I received the replacement and it was better than the second but not as good as the first. If you get a good unit that is bright enough then it is a 5-star deal. But QC seems to be hit & miss.

Works really well with my gun and very accurate very high quality
