The AR15 trigger guard pins are an essential component of the gun, as they help secure the trigger guard in place and prevent the guard from becoming loose during use. There are two main types of AR15 trigger guard pins: Mil-Spec and Non-Mil-Spec. The two types have some differences in terms of size, material, and design.
Mil-Spec trigger guard pins are typically made of steel and have a slightly larger diameter than Non-Mil-Spec pins. They are designed to be used with the original AR15 trigger guard and are often marked with a “mil-spec” stamp. Mil-Spec pins are designed to provide strength and durability, making them suitable for military applications.
Non-Mil-Spec trigger guard pins are usually made from aluminum, and are smaller in diameter than Mil-Spec pins. They are designed to be used with aftermarket trigger guards, and are typically not marked with a “mil-spec” stamp. Non-Mil-Spec pins are designed to provide a lighter weight option for those looking to customize their AR15.
Overall, the main difference between the two types of AR15 trigger guard pins is their size, material, and design.

Pros and Cons of Using Both Types of AR15 Trigger Guard Pins
The AR-15 is one of the most popular rifles in the world, and one of the most important components of the rifle is the trigger guard pins. There are two main types of trigger guard pins, the standard type and the enlarged type. Each type of pin has its own advantages and disadvantages. So it is important to understand the pros and cons of both types before making a decision on which one to use.
The standard type of trigger guard pin is small and lightweight, and it is designed to fit the standard AR-15 trigger guard. This type of pin is often the preferred choice for most shooters, as it does not require any modification or alteration to the trigger guard. However, the downside of this pin is that it is not as secure as the enlarged type. Because it is smaller, there is a greater chance of the pin becoming loose or working its way out of the trigger guard.
The enlarged type of trigger guard pin is larger and heavier, and it is designed to fit the enlarged AR-15 trigger guard. This type of pin provides a more secure fit, as it is less likely to become loose or work its way out of the trigger guard. The downside of this pin is that it requires modification or alteration to the trigger guard. This can be time consuming and potentially dangerous. It is not always easy to know which parts of the trigger guard need to be modified.
In conclusion, both types of trigger guard pins have their pros and cons. The standard type is lightweight and easy to install, but it is not as secure as the enlarged type. The enlarged type is more secure, but it requires modification to the trigger guard.
