Diamondback DB15 Carbon | 5.56 NATO | 10″ | SBA3 | DB1916K001

The Diamondback DB15 Carbon is a compact AR-pattern pistol chambered in 5.56 NATO built for controlled, close-range work. It features a 10-inch Chrome Moly Vanadium barrel with a 1:8 RH twist, a 9-inch PC M-LOK handguard, and an SB Tactical SBA3 pistol stabilizing brace on forged 7075-T6 receivers. This configuration suits precision-focused range training and practical pistol competition where a short, maneuverable platform is an advantage.

For a matched optic under $1,000, consider a Vortex Strike Eagle 1-6×24 — it provides a versatile zoom range and clear glass for both close and intermediate distances and pairs well with the DB15’s geometry and sight radius.
