Key features and what they mean in the field

The DIAMONDBACK DB-15 ships chambered for 5.56 NATO / .223 Wylde, offering flexibility between common 5.56 NATO ammunition and tighter .223 Wylde accuracy when using match-grade loads. Its free-float M-LOK handguard preserves barrel harmonics for improved consistency and gives direct attachment points for lights, grips, or bipods without adding unnecessary weight.
