Quarter Circle 10 Pistol MUR Upper Receiver

Posted on June 29th, 2016 by ar15news

For you Pistol Caliber builders out there….I just saw that the new Quarter Circle 10 Pistol MUR uppers are back in-stock. A few of my buddies have these and they match up very nicely to the QC10 billet lowers. The part that makes these different from other uppers is that VLTOR made these specifically for QC10 with a slick side wall with no forward assist along with a taller ejection port to allow extra ejection clearance for rounds from 9mm up to .45 ACP. If you’re looking for a great upper to complete your Pistol Caliber build,¬†this is a great option. Check them out at
