RCO/ARCO/MRCO sights not working properly with TRG rifle
Closed, ResolvedPublic

Description

I don't know if this is supposed to happen, but there is a large error in the bullet drop predicted by RCO/MRCO/ARCO sights with the TRG rifle.
A simple experiment is shooting a target at 500 m distance in VR Arsenal.
When you use the RCO sight and aim for the 500 mark the bullets pass way high - in fact the bullets hit when you are close to the 300m center mark (more than 100 m error).
This DOES NOT happen with the MX, Katiba or Mk20 rifles (and the Mk20 is 5.56 caliber also). For all those the sight work as intended.

Steps To Reproduce

Always reproducible, but as an example:
Open VR Arsenal, select TRG-21 rifle with a RCO scope.
There will be a soldier standing 500 m from you.
Shoot with TRG-21 rifle using RCO scope.
The actual bullet drop is very different than the predicted.

Additional Information

Now comes the funny part. The scopes are zeroed on their middle point on their standard range (300m i think just check the zeroing) the section drawn on the scopes are zeroed for the standard ammunition used in Arma 3 Vanilla : 6.5 mm Grendel.
So the scopes differ for any other caliber

I may be wrong, I'm no ballistics expert, but I doubt your claim about the scope difference for other caliber.
Let me explain.
The Mk-20 rifle is 5.56 caliber, the same as the TRG, and the RCO scope is nicely zeroed, i.e. fully usable. Check the screenshot:

How on earth there's such a big difference for two similar rifles using the same rounds? :)

Hello.

Thank you for the report. The TRGs accuracy should be fixed in the next update of the game.
