In addition to its functional benefits, an integrated trigger guard can also enhance the overall appearance of your AR15 rifle. The sleek and seamless design of an integrated trigger guard gives your firearm a more polished and professional look. This can be especially appealing for those who take pride in the aesthetics of their firearms. When selecting a lower receiver with an integrated trigger guard, there are a few key features to look for.
