Proper Installation of Gas Block and Gas Tube
Building your own AR15 can be a rewarding experience, but it can also come with its fair share of challenges. One common issue that many builders run into is the proper installation of the gas block and gas tube. This crucial step in the build process can greatly affect the performance of your rifle, so it’s important to get it right. In this article, we’ll walk you through the steps to ensure a successful installation.
First and foremost, it’s important to make sure you have the right tools for the job. You’ll need a torque wrench, a set of punches, a hammer, and some anti-seize lubricant. It’s also a good idea to have a vise block to securely hold your upper receiver in place while you work.
Before you begin, double-check that your gas block and gas tube are compatible with each other and with your barrel. It’s crucial that they fit together properly to ensure proper gas flow and reliable cycling of the rifle. If you’re unsure, consult the manufacturer’s specifications or reach out to a knowledgeable gunsmith for guidance.
