## Questions & Answers

**Q: Is this the genuine Mag Pul for 5.56 AR15, or the Airsoft version?**
A: As you should be. This is not the real thing. Check the size chart. 4.25mm will NOT fit on a 5.56 AR15 rifle. The top rails are standard 5.23mm on an actual AR

**Q: is this real Magpul?  or it is a PTS Magpul?**
A: This is not real,magpul commented on this subject

**Q: Does this site have two rear aperatures..one larger than the other and if so how do they work..how do you change from one to another.**
A: Yes they do. It work similar to the A2 rear sight. You just flip it up or down depending on the aperture you want. Hope that helps!

**Q: How many slots does it take on the rail?**
A: One but it covers some up when laid down.  I had room for it and a Red Dot scope on the rear rail.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Solid fit
*by D***E on June 29, 2025*

Rock solid and the original MBUS. Be aware that these slide over the pic rail after removing the screw. The attachment point is not two pieces as in most pic rail applications. This is important is you have a pic rail that is finished in Cerakote or something similar. This makes the rail slightly thicker because of the finish & makes installation slightly more difficult.

### ⭐⭐⭐⭐⭐ YOU CAN BE SURE YOU'LL APPRECIATE THE FINE CRAFTSMANSHIP AND EASY INSTALLATION ! C.W.N.
*by C***. on June 26, 2025*

IT WORKS ! VERY PRICEY BUT WELL WORTH IT WHEN COMPARED TO OTHERS I'VE BOUGHT !

### ⭐⭐⭐⭐⭐ Great to pair with fixed sites
*by K***R on June 14, 2025*

The install was a little tough, but seats firmly in place and pairs great with fixed sites. It folds down, out of site.
