Ok so Its never gonna be detected if you think it will you fail...

Get a scope or a sniper or a gun that has a built in scope...
Go into scope mode
Get a piece of tape and put it over your Dot in the middle of The screen not big.
Get a knife or some thing and be careful and make a small hole by cutting around where The dot is.
Take the extra tape off.
Then don't scope
Good luck owning without aiming....
