AR15 trigger guards are a simple yet important innovation. Rifle triggers are fairly delicate and aren’t built nearly as ruggedly as other exposed portions of the rifle. This is why it’s important to protect the triggers from damage with the help of AR 15 trigger guards. These quality, affordable items also help to prevent the trigger from accidently being nudged or bumped which can cause the firearm to fire at any time.These products can vary in appearance and material, but they all have their main purpose in common – to protect triggers. They very simply form a loop around the part and are typically made of plastic, metal or any other suitable material. To operate this part of the rifle with a guard on, simply place your finger inside it, in front of the part and do your thing.
