When compared to installing an AR barrel mounting the gas block and gas tube may seem easy, but when it comes to creating a rifle that’s reliable doing it right the first time avoids significant problems in the long run.
Looking to switch between suppressed and unsuppressed modes for your direct-gas-impingement AR-15? Patriot Ordnance Factory has a gas block that can help.
Though the AR-15 is one of the most accessible and easily assembled firearm designs, specialized tools like the Real Avid Master Bench Block can streamline the process.
