- When you receive your barrel you will notice the gas block is already in place but only slightly tightened. Grab a 5/64 allen wrench and remove the gas block from the barrel. Use a soft hammer and tap gently until it comes off. When the block releases from the gas port area slide the lo pro over the remainder of the barrel easily until it clears. Now that the gas block is completely off you can install the barrel using your barrel nut. Be sure to follow the manufacturer's instructions for torque and use the correct tool.
It is advised to put some oil on the barrel to ease installation. Center the gas block with the upper receiver and slightly tighten back the screws. Now it is time to install the roll pin through the previously drilled hole in the bottom of the gas block. Hold both the roll pin and your roll pin starter punch, size 4s, in the same hand. Hammer the roll pin until it is even on both sides of the gas block and stand back and observe your beautifully crafted barrel supplied by Ballistic Advantage.
- Note: After installation, if the gas block appears canted, loosen the set screw, use the soft side of the mallet and tap the gas block into the correct location. Once the gas block is in its proper location, secure your set screws.
