"The semi-auto AR-15 that we know today has been produced by Colt since 1964 and remains hugely popular with civilian firearm enthusiasts. Although the design proved reliable enough to stay in use over more than half a century, some improvements can be made to further reduce the risk of jamming and other malfunctions.
On of such methods is installing a custom Upper Receiver by Triarc. These receivers are machined with tighter tolerance standards resulting in smoother operation of your AR-15."
