Hey all.

Been a long time since I have done any serious work with the FAL platform.

Finally got mine out that has been in hiding for a while, full rifle length, and I have run out of up in the front sight post while still being 5-6" low at 50.

Base on a quick dial caliper measurement, my front post is already ~.020" shorter than the shortest post offered by DSA.

Rifle does have the Holland style rear sight which I like for its simplicity, and understand that it should be zero-d at 250.

But, being close to 3x height over bore low at 50 sure doesn't seem right?

Am I doing something wrong?

The only other variable I can think of to consider is that I am running an AAC 762-SDN6 suppressor way out there on it.

I wouldn't think that to be enough barrel deflection at 50 to give me the results I've ended up with, but perhaps I am over estimating FAL barrel rigidity?

Did you try without the suppressor?  What ammo?

Honestly, the suppressor causing that much POI shift didn't even occur to me until I was typing out the post.

Will try next time I make it out.

Was zero-ing with mostly Magtech M80, think I ran a mag or so of the last of some old chilean surplus just to burn it up.

Just using the bipod can give a significant POI shift so I'm sure the suppressor could have that effect as well.

If it's not that. swap out the holland rear sight for the standard real sight.
