No. While I have a gunstock, I can say it can improve your aim, it isn't necessary, and I rarely use mine. For one, it makes handling equipment more difficult. Second, it really puts pressure on your shoulder. While nothing compared to a rifle's recoil, it will still get sore after repeated long sessions. The final reason is this, you don't really need it. Suppose you start playing a VR shooter without a gunstock. In that case, you will, with practice, come to intuitively hold your hands like you were actually holding a gun, including turning. Still, a gunstock may be a good purchase for you as it will significantly improve immersion and truly does assist in aiming. Especially a novice to proper gun stance and guns in general. It will help you build muscle memory for when and if you remove the gunstock from your arsenal.
