I am awaiting my AAR for arrival. I bought the RRA tactical operator. My question is on the front sight. I was planning to install a set of Troy back-up iron sights, but the store told me today that the front sight may not be very easy to remove from the rofle. I have zero experience with an AR and wanted to ask some opinions on this. I do plan to install a holographic sight but wanted the option of using the flip up iron sights as well....

Y do u wanna take out the front sight? leave it and just use rear buis, no ?

Leave the front sight post on, just get a rear BUIS. You can still use a holographic sight with the front sight. There is nothing wrong with leaving it on, and it will save you the hassle and money.

Ok, that's all I wanted to hear! Appreciate it!

+1 on leaving the factory front sight. They are pinned on and more secure then if you were to remove it and go with a clamp on

 

Then again that maybe a moot point if the rifle has a perm attached brake- unlikely the front sight would come off over it. If it's a non threaded crown then you could in theory swap parts.. But why void a warranty on a new rifle (assuming it has a warranty of sorts) YMMV
