A good sound suppressor such as Echoless-80 will help you lay low on the radar. It also has different qualities that give this AR high Bullet Velocity, increased range, and better recoil smoothness. This attachment also backs the low range of the ARs in WZ2.
Moving down to the barrel attachment. The long barrel 24.4″ Bruen S-620 will provide bullet stability and accuracy due to its heavy weight. If you are into improving the Hip Fire accuracy, this attachment will also help with that.
The heavy recoil of the AR in WZ2 can be minimized using the Commando Foregrip underbarrel attachment. The heavy inner texture of this attachment allows you to have smoother and more accurate shots.
The perfect shot of any kind requires an excellent vision. We have chosen the Cronen Mini Pro, which goes nicely with this gun. You can find the enemies quickly as the view provided by this attachment is perfect, allowing you to take down enemies quickly.
Finally, the 42-round mag will improve your poking potential by providing you with more rounds per magazine. You can clutch crucial movements due to this attachment.
