Correct front sight post for carry handle rear?

There's even taller than .040 if needed.

If you find the KNS piece kind of thin then contact JSE Surplus or even better Brownells. I’ve purchased taller front sights from both of those places.

I bought a 6920 last year. Front sight base was not F marked, but I threw a carry handle on it and it sighted right in.

They don't put the "F" mark on their "F" height FSBs anymore. But the FSB on the 6720 is not "F" height.
