We Know What It Means To Be a Left-Handed Shooter

At Keystone Accuracy, we have a great deal of self-motivated innovation for the left-handed rifle to accommodate target and tactical shooters alike. We are always searching for great left-handed custom products. We contract custom chambering and custom machining with manufacturers to produce exclusive left-handed products.

Left-Handed Billet Upper Packages

We get several phone calls regarding the excitement around the left-handed billet upper packages. One thing to keep in mind when building a left-handed upper is that since the bolt rotates in the opposite direction as the standard AR bolt, locking lug chamfers are installed on both sides of the ambidextrous or left-handed barrel extension to aide in the bolt to go fully into battery. These chamfers also meet the chamfers installed on the bolt lugs on a left-handed bolt.

Standard vs. Ambi Barrel Extension

We have spoken to people who have used a standard barrel extension when building a left-handed uppers. However, this practice may cause you to encounter out of battery problems in starting the bolt in its rotation since the bolt lugs are forced to ride against sharp 90-degree locking lug rather than a chamfered one in an ambidextrous extension.

The people we have spoken to that have used a standard extension with a left-handed bolt say that they have encountered no problems. However, as a bit of insurance on a rifle that functions well, we choose to use an ambidextrous extension on every left-handed rifle that comes out of my shop to provide a higher quality of customer satisfaction.


Stag Arms Designs

Stag Arms, a firearms manufacturer as well, has finally come out with a left-handed Stag-10 upper-receiver and bolt-carrier group that is DYNAMITE! Stag uses a proprietary design that is a hybrid of the DPMS style mags and the DPMS high-rail type float tubes. They also use a receiver design that is reminiscent of the rear design of the original AR-10. The lower uses all AR-15 parts, except the takedown pins. In short, it's truly an excellent design from top-to-bottom.
