Diamondback DB-15: Precision Shooting Semi Auto with 30-Round Mag

For shooters seeking a value-driven semi-automatic rifle that balances accuracy, ergonomics, and modularity, a certified used option can deliver near-new performance without the new-gun premium. Tactical operators, range regulars, and budget-conscious buyers benefit from rifles that arrive ready to run and backed by a solid return policy.

DIAMONDBACK DB-15 arrives configured with a practical parts kit: one 30-round magazine, a Rogers adjustable Superstock for rapid shouldering and cheek weld adjustment, a PSA upper providing a dependable platform, and a 1/7″ barrel twist that stabilizes a wide range of bullet weights.

Design and Key Features

The DIAMONDBACK DB-15 is a Semi Auto platform built for practical accuracy. The 1/7″ barrel twist is a versatile choice: stabilize heavier projectiles for precision work while remaining compatible with common mid-weight loads at the range. The included PSA upper pairs with Diamondback’s lower geometry to offer consistent lockup and modularity for future upgrades.

Stock and Handling

The Rogers adjustable Superstock improves fit across shooters of different statures and allows quick, repeatable adjustments for optic co-witnessing or iron sight indexing. For defensive and precision drills, that adjustability shortens transition times and improves cheek-to-stock consistency.

What Comes in the Box and Buying Confidence

Each DIAMONDBACK DB-15 Certified Used unit includes one 30-round magazine and carries the Certified Used stamp, meaning the firearm is held to a very good to excellent condition standard. Certified Used firearms include a ‘no questions asked’ return policy, making this an attractive option for buyers who want assurance without overpaying. The listed price is $549.99.
