Barrel
The 16 inch barrel is chrome lined steel and a 1:7″ twist.
Stock and Fit

Size and Handling
A steady rest, a good sling and practice from field positions will help you shoot it well.
Ammo and Practice
Try a few brands and bullet weights to see what groups best in this rifle, then buy enough of that load to practice and hunt with the same ammo.

The 5.56 NATO chamber also fires 223 Remington, so you can shoot inexpensive practice ammo and premium hunting or defensive loads.
Target Shooting and More
This rifle is a good fit for target shooting, training and, where legal, home defense or hunting. Add a quality optic or red dot and a sling, and confirm your zero.
Optics and Accessories
Plan on quality scope rings or mounts, a sling, a hard or soft case and a cleaning kit. A bipod or shooting sticks help a lot for steady shots in the field or at the bench.
Buying Tips
Budget for quality optics or sights, a sling and ammo, and confirm your zero at the distances you expect to shoot.
Care and Value
Clean the bore and action after each range trip or hunt, keep moving parts lightly oiled and wipe the finish after handling. A well kept Shadow Systems holds its value.
State Laws
Some states limit semi-auto features, magazine capacity and hunting calibers. Check your local law before you buy. Pennsylvania buyers can transfer at our Collegeville shop or at any FFL.
