Can't you help me look at this?
Don’t use a knife with a sniper rifle, but a pistol, unless you are very confident
Being a sniper requires tenacity.
Submachine gun recommendation: Tenacity or Togetherness
It lacks a long gun and a burst rifle. The 141 is originally a long gun. After looking at your accessories, I found that you want to use it as a short gun. Change the accessories, and then add an hvk gun. This gun is very recommended for scalping. You use this set of accessories, which is best for medium and close range. Then you'd better equip it with a single-shot sniper. AMR is a continuous-shot sniper and its penetration is very poor. You need to wear it frequently when shooting explosive snipers.
