What Size Roll Pin Punch for AR-15 Bolt Catch?
When it comes to maintaining or modifying your AR-15 rifle, understanding the correct size of tools is crucial. One such tool is the roll pin punch, which is used to install or remove roll pins from various components, including the bolt catch. In this article, we will delve into the details of the appropriate size for a roll pin punch for your AR-15 bolt catch, ensuring that you have the right tool for the job.
Understanding the Bolt Catch
The bolt catch is a critical component of the AR-15 rifle, as it holds the bolt in the open position during disassembly. This allows for easy cleaning and maintenance of the firearm. The bolt catch is secured to the upper receiver with a roll pin, which is a small, cylindrical pin that is inserted into a hole and deformed to hold it in place.
Why Use a Roll Pin Punch?
A roll pin punch is a specialized tool designed to install and remove roll pins. It features a pointed tip that fits into the end of the roll pin, allowing you to apply force to either install or remove the pin. Using the correct size roll pin punch ensures that you can perform the task efficiently and without damaging the components.
Identifying the Correct Size
When it comes to the roll pin punch size for your AR-15 bolt catch, it is essential to use the correct diameter. The bolt catch roll pin is typically 0.187 inches in diameter. Therefore, you will need a roll pin punch with a shank diameter of 0.187 inches to fit properly.
It is worth noting that there are different types of roll pin punches available, such as those with a straight shank and those with a curved shank. The straight shank punch is suitable for most applications, including the AR-15 bolt catch. However, if you are working with a curved component, a curved shank punch may be more appropriate.
Choosing the Right Roll Pin Punch
When selecting a roll pin punch for your AR-15 bolt catch, consider the following factors:
-
Material: Choose a punch made from high-quality steel for durability and longevity.
-
