Best on the market.
An absolutely excellent piece of kit to install. Even if you already have telescopic sight fitted, the front sight can still be installed if not both. Reason, batteries can and do fail even when you're not expecting it. These are the best back up at the very least. As a primary sighting system these are the best and faultless flip-up system I've ever purchased. The price cannot be beaten for this kind of quality.

Doesn't fit on 20mm RIS
Had to return this as it simply doesn't fit on a standard 20mm rail. Probably could with some sanding but wouldn't expect to have to sand a brand new product, especially at this price point.

doesn't fit, however good quality for price.
Seems really good solid quality... However, doesn't fit standard 20mm picatinny rail. Had to spend abit of time shaving/sanding down in order for it to fit and operate as it should.

Good value for such a low price.
Would not want to fit them to a firearm, but perfectly suitable for an airgun. Solidly made for the price.

Brilliant seller
Solid product, no issues with the item, I did however receive x2 back sights so the seller sent a front sight to me straight away free of charge, brilliant service thank you

Not great
Completely plastic, front sight post somehow broke off after two game days, couldn't get the elevation adjustment to go high enough to be properly zeroed for my gun, the rail mount was extremely tight and barely fit. If you can get them on your gun then they work, barely.

Doesn't fit rails.
The product is made of average strenght polymer, however, it wont fit any of my rails as its too tight. Low quality item.
