Magpul MBUS Sights

My very first AR(Bushmaster 308 MOE) came with Magpul MBUS(Magpul Back-Up Sight) on the back.  So did my second AR(M&P Sport II).  Both of those rifles had the A2 front sights:

Triangular A2 Fixed Front Sights

I actually prefer them.  They don't really get in the way of the sight picture for me, and they seem durable.  However, when I bought the Blackout upper by Bushmaster, it came with no sights at all.  

So I had to get the "MBUS" front sights for the first time.  Already had extra rear sight I can pop-on behind the EOTech red dot for cowitnessing(you can use backup sights by sighting thru the optic).

I still prefer A2 front sights, but this works beautifully.
