Review: 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.

### ⭐⭐⭐ Cool Sights, Difficult Installation
*by W***. on 8 November 2025*

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!
