This is a Bullet icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,000 icons, all in the same style and quality.
The bullet icon can be used in a variety of ways. It can be used in articles and tutorials that talk about a number of gun related topics. Examples of such topics include gun safety, gun regulation, and the history of arms.
There is a variety of icons to choose from.
