There are plenty of other options out there to choose from for flip up front and rear sights for your AR15, but probable 95% of our flip up sight sales are all the Magpul ones. I think many gun manufacturers know that after spending money on a firearm, then choosing and optic, not many people feel the need to spend $200 on a front and rear sight combo which makes the Magpul MBUS sights such a staple in this industry. For under a $90 you can get a set from Magpul and I rarely hear of anyone complain about them. With the many variations of AR15 designs out there, there are some pitfalls that people run into when picking out rear and front sight though.
When you are choosing a rear sight, you need to be aware that if you are intending on putting on an optic like a magnifier, you have to make sure it’s going to clear, many times people end up having to get another lower profile rear sight, I know I had that issue. For front sights, if you have a gas block, make sure you get the Magpul MBUS flip up sights like the Pro sight or you’ll find out real fast that you won’t be able to zero your rifle properly and if you didn’t figure that out soon enough, you’ll end up melting your front sight off if you heat up your gun on a firing range. Know your carbine and what all the variables are and don’t just think you need any front and rear sight. We never like to run out of these in our Showroom because they always move so fast.
