Make your AR15 to run 9mm using a Foxtrot Mike side charging upper.
This video demonstrates how to run an AR15 9mm using specific aftermarket components. If you have an existing lower, this setup offers a practical solution. We test the Foxtrot Mike side charging 9mm upper on an Angstadt Arms Glock mag lower to evaluate compatibility and performance.
We also cover the use of a 9mm mag block for those who need to adapt their standard AR receivers. By utilizing a dedicated mag block, you can switch calibers efficiently without needing to assemble an entirely new firearm from scratch. This walkthrough is intended for shooters looking to optimize their current AR9 or expand their platform capabilities.
Subscribe for weekly firearm configuration breakdowns, and let me know in the comments if you prefer dedicated lowers or mag blocks for your setups.
