I have 2 STI's (DVC 3 Gun & Apeiro) both run fantastic. Not a single issue with either. Apeiro has a smoother action but I highly recommend both. I looked around and found deals here on the forum & Gunbroker. New, unfired I didn't pay more than $2,400. Atlas are phenomenal guns but even the Titan is $3,700. Save 5% and your at $3,500. That's a few extra mags and a lots of ammo. Sent from my SM-G928V using Tapatalk
