In this episode of TFBTV, James visits Thunder Ranch and speaks with the guys from Aero about their "EPC" or "Enhanced Pistol Caliber" carbine AR-15. As of right now, they have a prototype up and running with 20,000 rounds through it, and James got to try it out at the Thunder Ranch Urban Rifle Course! The EPC carbine is going to be offered as a partially built lower for $150 all the way up to a complete rifle. It will be available in 9mm, 10mm, .40S&W and .45ACP, and yes, it will take GLOCK mags.
