UniqueFire Red Illuminated Dot Mini Compact Holographic Reflex Micro Scope 20mm Rail Mount (3MOA)

Bright enough on half power in good light ,fits the 20mm rails perfect, does what it does

Excellent value for money, once fitted quickly zeroed.. Spot on! Delivery quick too :))

Well, things started out well because the sight was small and compact - it looked good mounted on a Glock -non-block back CO2 pistol. After about a month I decided to upgrade to a block back Glock and after two outings with it to the range, it has stopped working completely. The blowback action on the Glock isn't even that strong compared to other CO2 pistols I have used. Now it will not turn on at all. So disappointing.Do not buy this if you intend on mounting it on any form of blowback gun.

I bought this and was dissappointed to find that it was DoA, however after trying the spare battery provided it was just that it was poorly made inside and the negative contact spring did not complete. It's lucky I'm vaguely technical, and have a multimeter to hand. You shouldn't have to do this for a new product, but it is cheap so buyer beware.I would have given four stars if it weren't for this issue as the unit itself feels solid and is a good low profile sight which i use for paintball (less chance of a ball breaking the lens).EDITThe seller contacted me after I wrote the original and replaced the item free of charge, this unit functioned perfectly. Thanks Angela for your great support on this product.Hope this helps guys.

Excellent buy.I have bought two.

It’s okay- might be great for low light levels but it’s a bit crappy in daylight.

Struggling with configuring this. Can't move the dot any further left. Only getting 3 turns from one side to the other. Other than that the dot is decent. Nice and bright with good clarity. Good value for money.

Not the best as you can’t adjust the red dot to where u need it to be don’t waste your money
