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

I really do love the look of these MBUS –Magpul Backup Sights– style iron sights. The flip-up action is really cool for how they are spring loaded, but the only major downside is that they fit VERY tightly on any 20mm Picatinny RIS/RAS rail, and you really have to push them on hard to get them to sit where you want, almost to the point where you don’t even need to secure them with the internal hex screws with a hex key (that they didn’t come with). I do like them though. And as I can barely find Airsoft MBUS style sights anywhere else, I really still like them!

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.

Love it!

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.

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

Cheaply made not what I was expecting to be
