551 Holographic Sight Red Green Point / Dot Sight Scope, 10 Levels Brightness, Fits Any 20mm Rail, Black

Great purchase brilliant

This is my second cheaper red dot sight purchase and if I'm honest it's not as good as my first one.This looks the part, is quite bulky considering the smaller options available. But it does sit nice ontop of a good sized Airsoft aeg.Easy to mount, it's just a simple screw. There's adjustable screws for zeroing it in. The controls are easy to see and simple. There's only one option of display type, Vs other sights which have several options. This has different brightness options and red or green options. The brightest output is good enough for daylight games. The green is better for night games.The biggest issue is display itself I slightly blurred. It's not as clear as my other sight, so that's a disappointment really. It's not going to stop it from doing the job and my Airsoft isn't the most accurate or expensive either so it will do I think. If I find it a problem after the first site visit I'll report backUPDATE. Tried it outside and was amazed at how utterly rubbish it is. You cannot see the red dot in even the slightest sunlight. I've returned it as it's not usable outside at all.

I really wanted to like this, but unfortunately whilst I could adjust the windage the elevation adjustment was defective, full refund so no hard feelings, the optics were excellent for the price if you manage to get a fully functional unit I've no doubt it will be a cracking dot sight
