FIRST LOOK – Quarter Circle 10 Pistol Caliber MUR Upper

Posted on November 6th, 2015 by ar15news

Quarter Circle 10 has been working hard to bring multiple Pistol Caliber upper options to market that will match their billet Pistol Caliber lowers. First up is their collaboration with VLTOR to make a “Top Charging” Pistol Caliber MUR upper. Its a slick side upper with a smaller pistol caliber opening. “Top Charging” meaning it utilizes the standard AR-15 Charging Handle. These open for pre-order. Their website says 1-4 weeks but I was told by QC10 they they should ship by the end of next week. Price will be $179.95. If you’re looking for a very nice traditional pistol caliber upper for your QC10 or other builds, check out
