Tactical M4 AR15 AR-15 Front and Rear Folding Sight flip up Rapid Transition Backup Sight for Picatinny Rail

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.

did'nt fit a 20mm weaver rail/picatinny had to file the sights down where they grip on to the guns rail.to make them fit.other than that good sights

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.

The product is made of average strenght polymer, however, it wont fit any of my rails as its too tight. Low quality item.

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

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

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.

Heart easy to fit and set up and the aluminium construction is a bonus.
