How to adjust the ultra-stable sensitivity of m4 16?

The sensitivity of the finale, and the sensitivity of the shooting lens is six times that of the pressure gun. This is the adjusted sensitivity and can be copied directly. Our lens-doubling guns generally use three, four and six mirrors, and the six mirror is rarely used (because the player has adjusted it three times). We mainly talk about three mirrors and four mirrors. How do players adjust these two things?

You can adjust the interval from 15 to 3-5, and then shoot at the target to see the results, so you can quickly adjust your sensitivity. Accessories are also important for the stability of firearms. We take M4 16 and SCAR as examples. The accessories of these two guns are recommended to be vertical handle and muzzle compensator, because it can minimize recoil and concentrate trajectory.

How can your own sensitivity be considered a good dancer? This means that if the AKM trajectory of the triple mirror focuses on 20 rounds, and the triple and quadruple bullets of M4 hit a line with little jitter, then your sensitivity has been adjusted.
