A2 clamp on front sight gas block

[tommyid1]

How far off will the sights be if I use the Armalite clamp on front sight with a flattop upper I I don't get the .040 taller sight blade? The thing is I want to run a hiviz front blade.

Thanks

nobody has experience with this?

I'm sure you can figure out how to zero it, but adjusting for range will be another thing. This assumes you understand why you need the .040" higher post.

I figured it wouldn't make that much I a difference as far a adjustability how much would I be loosing in elevation adjustment? My guess is not mug especially on. 16" barreled carbine

Thanks

I have the armlite on my .22lr cmmg upper. Just cranked the front sight post down further until I had a good zero at 33 feet. Haven't shot it outdoors yet but it zeroed just fine for elevation. Left right was more of a pain in the butt. Kept tweaking it to far and then over correcting the other direction.
