Product Description

Mil-Spec correct, thick walled upper receiver
The rigid upper receiver will increase reliability and accuracy
Extends the life of compatible component
Reduced port size for pistol caliber cases

The Quarter Circle 10 upper receiver is a thicker walled version of a forged Mil-Spec receiver. Since Vltor manufactures this upper in the manner they do, it is inherently more accurate when compared to a Mil-Spec upper receiver. This is a great option for anyone that is interested in building or improving upon their pistol caliber carbine. Any standard AR15 upper will work for a pistol caliber build, but we recommend using pistol specific parts when possible.

Best Pistol caliber upper there is.

Posted by Big Daddy on 7th Jul 2017

I've been building pistol caliber AR15s for a few years now and these are the best I have used. It solved an issue I have had with Colt magazine pattern 9mm ARs. Due to the enlarged ejection port it eliminates potential problems with the ejection of spent shells. They are different than rifle AR15s and the operation is recoil not gas, also the physical dimensions of pistol cartridges are different. Especially the .45ACP which is so much shorter and wider.
I will also say that the cost and speed of shipping by Strong Side Tactical was amazing, best I ever experienced.
Great upper for pistol caliber.

This is a wonderful upper for a pistol caliber build. It has clean lines and good machining. I'm glad I found one with the reduced port size.. purpose built for the job vs. adapting a 5.56. I have it on a ccmg lower works great.
