Title: Scoping my First AR15
Post by: Galeth005 on June 30, 2012, 08:23:28 AM
Ladies and gentlemen, it has been a while since i have had the unique pleasure of inquiring for your assistance.  however i find myself in the need of your expertise on my particular little problem.  I have a stag model 2T that i would LOVE to put a Red Dot or eotec reaction scope on.  well as we all know the Model 2T has a fixed front site, and this is where i run into the problem.  HOW difficult would it be to remove the Iron Front site and replace it with a flip down site?  Or should i just slap the scope on there and get a spacer/higher rings to go above the iron site?

that's my new toy, will be adding more toys to it later.. just need a scope first and foremost

The front sight comes off easy.  Just drive the taper pins out and remove the gas tube pin.  Then just tap the sight off the muzzle. You will of course have the remove the flash hider first.  If you get a fold down front sight, get the clamp on style.  I've had mine on for about 6 months now and have had no problems.  Had no issues with gas ports lining up on anything like that.  If you go with a gas block with a rail, make sure you get a metal sight as the plastic one cant take the heat.

Regardless of the type of red dot sight you are going with just leave the front sight in place.  After the first few shots you will never notice it again until you need it.

If your red dot fails or you choose to not use it you can just flip your rear sight up and go.  At our three gun events most people that have a flat top and electronic dots have fixed front sights.  Some even use a fixed (non-folding) rear sight. 

In my opinion magnification is another matter.  Some people will leave the front sight in front of their optics with no problem, but I like my magnification above the front sight.  My three gun AR is set up with a fixed handle and fixed front sight.  I have a sight through mount for my magnification, and my red dot is mounted to the right side of the handle rail.  I can use iron sights through the scope rail on the handle; I can use the magnification by just raising slightly; and when I cant the rifle 45 degrees left the red dot comes in front of my right eye.  Also, with this set up I can go back and forth between open and limited class with just one thumb screw in the middle of the handle.

Before you invest time and money in changing your gas block and sight, mount the red dot and see how nice it is.

+1. The red dot and the existing front sight should "complement eachother",. That little hologram right at the top of your front sight can help tremendously in rapid target acquisition and keeping the gun in line downrange.

It maybe needed to use a laser bore sighter to ensure the front sight post is aligned at the right height with the red dot, and rear BUIS should be able to remain as intended, may require a front sight adj. tool. About $5-8.

I did it with mine, without a standard front sight but flat gas block.  With both of my flip up sights up, and red/green dot activated, and a laser bore sight in the muzzle, I started at 15 yds. and adj. until the BUIS, and red dot were on top of the laser bore sight, and walked it back to 25 yds. for zero, and locked it there.

I intended my AR for a CQB type AR, so zeroing at 100yds was not the intent, but can shoot and group minute of Dixie plate from the standing position at that range. (Minute of coffee cup saucer as ranges decrease)....

The bore sighter saved me ammo and did the "work" for me until I verified it at the range.

This may work for you. Like m58 posted, try it. It's still an AR and options and configurations abound.

Best of Luck
