| I have a barrel with a FSB installed that I wanted to turn into a dedicated .22LR upper. I was planning on tapping the gas port coming out of the aft of the FSB and installing a plug. Then, I though about the roll pin holes that usually hold the gas tube in place. I was thinking somebody may have made a plug that plugs the gas port and the roll pin holes. Or maybe I am worrying too much about gas/unburnt powder flying out of the roll pin holes. |
