The QC10 Ranger is a blast at the range or perfect for home defense. People who have a hard time shooting handguns will appreciate the additional contact points that a PCC offers for better accuracy and control. 

The QC10 receiver balances reduced weight and durability. The receiver is made from 7075-T6 aluminum that is then Type III hard coat anodized. 

People who try to build their own AR9s often run into problems with reliability. But Quarter Circle 10 specializes in AR pistol caliber carbines. So they have designed their own proprietary universal 9mm bolt assembly that functions smoothly and includes last round bolt hold open. That is so important in an AR9 to save wear on the firing pin, let you know when your mag is empty and make reloading simpler. All you need to do is slam in another magazine and release the bolt instead of reaching for the charging handle. 

The trigger on the QC10 is enhanced Mil-Spec and comes with a Magpul MOE carbine stock, Magpul MOE grip and Radian Talon abmi safety selector. 

Quarter Circle even throws in a carrying case so you have a space-saving way to transport this AR9 to the range. 

If you're looking to pick up an AR9, consider one from the guys who specialize in them. The QC10 Ranger is made for pistol caliber ammunition, not modified from a 5.56 platform. That means better functionality, reliability and overall performance.
