Can the LWRCi M6A3 front sight blade be replaced?

Hey, I’m looking to replace the front sight blade on the M6A3 gas block mounted front sight post, for an AmeriGlo night sight blade.

Can it be done? I’m assuming you’d need an AK sight.

Has anybody done this? Advice?

Help would be really appreciated.

ETA: I just realized this was the ‘‘AR General Discussion’’ not ‘‘Technical Discussion’’ forum.

Sorry.
