In real life zeroing is made by changing the angle between barrel and sight and its measured in moa. You're free to set zeroing at even very big angle. for example with m107 zeroed on 100 moa u shoot at aprox 2000m and its just 1.67 of degree.
So u cant say that i cant change position of tws sight more than 1 degree (1600m aprox)
I'm requesting changing zeroing restrictions to higher numbers for exampple for SOS and TWS up to 2600-2800 somewhere that high
