Default Decided on an AR now i need help with the front sight :)

Bought a S&W M&P AR15 instead of the Romanian PSL you guys talked me out of (THANK YOU ALLL). I've been shooting via IronSights but I dont like the Mag Pul Rear Sight that slides onto the top rail, it came with my AR (its a Flat top) I put a Quad Rail on the front and I want to mount a Red Dot but the Front Sight gets in the Way of anything I mount. I cant figure out how to get it off though, any suggestions? (if i come off as stupid its my first AR and i plead ignorance and hope someone corrects it.

You may not realize it, but the front sight is the gas block that feeds the gas from the fired round back through a gas tube to the bolt so the action will cycle. You can't just pull the front sight off without replacing it with something. You can however cut it down and reshape it. Your local gunsmith could also fit the gun with a new low profile gas block to replace the front sight. I wouldn't recommend a novice to try and fit one by themself. If not done right you'll have a nice single-shot rifle.

Of course many people use red dots scopes with their A2 front sights in place every day without any problem. All it takes is the proper height mount on your rear rail and you're good to go.

There is also a thing called cowitness where your red dot essentially works to confirm your sight picture through your iron sights. In that case, having your front sight in-place is essential.

Look around at this place and you'll see what I mean:

Even if you put a scope on it you will not see the front sight in the scope

Same with the red dot you will see it but it wont be in the way , even if the red dot fails you can flip up the rear sight and still see the front one thru the red dot , it wont need to be removed to use the iron sights

If you are set on removing the front A2 style site you can always install a new gas block with rail. This would allow you to install a flip up style front site and maintain a back up sighting system should your red dot give out on you.

Having iron sights front & rear is a must regardless you r putting red dot or scope.
IMO. I never remove my magpul sights whether i put my Eotech or Nikon scope.
