I'm not a gunsmith but I really like gun smithing. This was a fun build and I thought I would share it.

In this video I describe what I did to set up a reliable AR-15 pistol chambered in .338 ARC using parts from several manufacturers.

As always, your mileage may vary and I cannot show too many details on YouTube, but careful descriptions are given to help other recreational marksmen achieve a safe and reliable firearm.

Cheers!
