I had my Colt Match Target unbanned and I just realized that the FSB is F marked. How does that affect my POI?
I have not shot it since I unbanned it I will have to shoot it here soon to see. Would I need to replace it with a normal A2 FSB?

Thanks.

It will not make that much difference.  The F base will raise your front sight  .040 of an inch.  You may need to lower the post by that when you zero.  It's better to be .040 too tall than too short.

I had to crank my front post WAY down into the base to get it to sight in.

You can also raise the rear sight and re calibrate the wheel.

Cool, thanks I figured it would not be much of a problem.
