Key Features and Why They Matter

1/7 Twist Barrel

The 1/7 twist rate stabilizes a wide range of bullet weights, offering flexibility for heavier projectiles and modern loads. That twist profile supports consistent accuracy across defensive and target loads.

Adjustable Arm Brace and Muzzle Device

An adjustable arm brace improves shooter stability and ergonomic fit for different users and shooting positions. The included muzzle device reduces perceived recoil and can aid in faster follow-up shots in practical drills.

Ambidextrous Controls

Ambidextrous safety and controls are essential for fast manipulation under stress or for left-handed shooters. The SD-556’s controls allow intuitive operation from either shoulder and streamline transitions during training.

Handling, Accessories, and Fit

Included items — original box, manual, and two 10-round magazines — make this purchase range-ready from day one.
