From the manufacturer
KNIGHT'S ARMAMENT SR-25 K3 7.62 NATO/.308 ASSEMBLED UPPER RECEIVER The SR-25 K3 is the commercial variant of the M110K3; purpose-built to enable rapid precision fire at mid-range, with a form-factor that is easy to carry, fast to employ, and readily adapted to support a broad array of applications.

Fully ambidextrous controls offer left-handed users the ergonomic advantages inherent to the AR-15 format, as well as giving all users alternate methods of manipulation to increase efficiency of movement.
