The Quarter Circle 10 Colt 9mm lower receiver is, quite simply, the finest pistol-caliber AR platform available. Precision milled from 7075 billet aluminum, each one of our receivers is hand-inspected at every stage of manufacture to ensure precision and quality. This is no poorly milled adaptation made from surplus AR-15 receivers. Our CLT9mm lower was designed from conception as a dedicated pistol-caliber receiver built around the Colt 9mm Submachine gun magazine. The Colt 9mm receiver is up to the task of delivering rounds on target with more accuracy and power than a handgun, all in a package that is tighter and easier to control than a rifle-caliber firearm. Form and function play equal roles in our design, and the CLT9mm not only runs like clockwork, it looks the part. With a simple yet distinctive aesthetic, the CLT9mm lower immediately draws attention, but also fits right in among other tactical weapons.
Just as in the lawless days of the American West, when having a rifle and a pistol chambered for the same ammunition made sense to lawmen, cowboys, and outlaws alike, today many officers of the law and private citizens recognize the advantage of running the same ammunition in both their primary and secondary weapons. The Colt 9mm lower carries this idea forward with our simplest, most traditional design. This simplicity and dependability is only part of what makes the GSF an obvious choice for tactical applications, home defense, or emergency situations.
Now, you can build your pistol-caliber platform with the peace of mind of knowing that every component is of the highest quality. Whether for home-defense, law enforcement, competition, or plinking, Quarter Circle 10 has you covered, with our philosophy of Made For- Not Modified. Each of our parts is engineered and manufactured with pistol calibers in mind, rather than modified from rifle-caliber components as an afterthought. We’re Quarter Circle 10, the AR Pistol-Caliber brand.
