ar-10 armalite carbine

[mussyhairhillbilly]

any eotech or acog suggestions for an armalite, ar-10 "a" carbine,? i dont' want to remove the fnt post from the barrel.

I don't understand how any of those relate to each other. What does an optic have to do with removing the front sight?

In my experience, you want approximately 1.4"ish inches from rail to centerline of your optic on an Ar10-pattern rifle. Prevents you having to cheek-hump the stock. So regardless of what optic you put on, you may need a riser

that's what i was afraid of, if i put an optic on, the frnt a-2 style post is the way, and in order to install a cheek-riser, after using a rail 3/4 riser, i would have to change the stock as well. oh well.

Is a low powered scope an option? Very easy to get correct height rings or 1-pc mounts........

 

[mussyhairhillbilly]

yes i do have a low powered scope, i'll try one of those one piece mounts.

The standard ACOG mount is about 1.5" above rail . An AR-10 rail is about .150 higher than AR-15

I wouldn't worry about the additional height ...I use std 1.5" Larue mounts for both Aimpoint , ACOG and magnified scope with LR-308

Finding the 1.4 inch unitized mount is harder . Badger makes one as does ERA Tac

I'm running an ERA that is 1.36" high and it works fine

Don't worry about the FSB ....it has nothing to do with the proper cheek weld / scope centering height . Regardless if you have fixed FSB or not, you still need the 1.4"

FYI - ACOG with FSB is fine....you may find it distracting but its in the bottom 1/3 of the scope anyways

Lots of pics online if you are curious to see

maybe i misunderstood the post.. i got the impression he was concerned with the front sight obstructing the view through his optic?
