Let's settle this factory zero issue. As expected, the SAR-21
has been discussed to death before. Found this old thread on sgf:

The point is, the factory zero slips and becomes useless, and in
the tactical sense you go to war with a personal weapon, not with a
weapon you find in a crate or on the floor like in a video
game.
Your personal weapon is a weapon you train with and have to go
through field conditions with.
And this is not under extremely harsh conditions or torture
testing but routine use.
So if something like "factory zero" can't last the operational
lifetime of the weapon, what does this say about it except it is a
gimmick? In fact plenty of weapons with intergrated scopes could
claim "factory zero" as a nice feature, and as a matter of fact
these weapons are factory zeroed.
Bt they don't make a big point about it because they know by
common sense such a thing is a gimmick.
In Reality - the fact still stand - if I need to ship brand
new rifles out to battlefield or reconditional factory rezeroed
rifles - to soldiers who can open the crate and shoot with it
without zeroing.
In reality- the bigger and more important fact stands that
soldiers will have to use their rifle in harsh conditions and over
prolonged periods, and practially speaking the zero will slip.
So what's the point? More importantly, "factory zero" does
not take into account the fact that each and every shooter is not
the same. To consistently shoot with your
Why not - that is still an advantage, which
few others can claim
!!!
Getting your facts wrong again?
Virtually all other modern firearms are factory-zeroed, but once
again they don't make a fuss of it. The SAR-21 is hardly new to
this practice. Your G36 comes off the assembly line zeroed to 200
meters.
The difference was that the SAR-21 makers were silly enough to
claim this weapon didn't need zeroing due to factory zeroing, which
was patently false. Before ATP there are still zeroing shoots for
the SAR-21.
This is because factory zero was never a subsitute for true zero
in the first place.
This is what the literature says:
The scope is factory-zeroed, and requires minimal further
zeroing to suit different users. This minimizes non-training range
time to zero the weapons and maximises live-firing training
hours
As for combat advantage there is practically none at all... in
fact you'll be probably worse of because the "standard" zero of the
sights will not suit you as perfectly as a weapon that you bothered
to zero on the range to your needs.
And of course the zero of all weapons, especially new ones which
have not been broken in will slip because the shooting
characteristics of the weapon will change over time as it is
used.
So what advantage does the factory zero give in practice? Unless
the SAF is in the practice of issuing non-personal weapons to their
troops straight from the box and sending them into battle without
time to prepare and personalize the sights to the users...
It provides none at all.
It's about the same as the lionnoisy claimed advantage of being
able to carry the SAR-21 like a handbag and "run for your life"
