Upgrading your AR15 to a free float forearm is one of the most common modifications shooters do. However, removing those pesky taper pins on the gas block can be a task. In this two part video series I'll show you how to change out the gas block and install a Seekins Precision Free Float Tube with minimal tools. My goal in these videos is to help the non professional so that they can do the modifications themselves. The only "specialized" tools I used were the AR-15 Armorer's Combo Wrench Tool, a Brass Punch Kit, and a barrel vise similar to the one below.
