The Heckler & Koch HK416 Slim Collapsible is a semi-automatic .22 LR rifle in matte black, weighing 8.6 pounds with an overall length of 32.7 inches. Its 16.1-inch threaded barrel takes compatible muzzle accessories, and aluminum upper and lower receivers carry an aluminum M-LOK rail for mounting add-ons. The collapsible synthetic stock shortens the package for storage, and the top rail is optic ready. A 20+1 capacity and one magazine come in the box, while an ambidextrous manual safety and charging handle serve right- and left-handed shooters.

For Pennsylvania buyers this rifle is a range and training choice rather than a hunting rifle. The state deer and bear seasons allow only manually operated centerfire arms and do not allow semiautomatic rifles, so the HK416 .22 LR stays at the range or the practice bench. It suits shooters who want the HK416 layout and an accessory-ready rimfire platform for plinking and skill building, and the economical .22 LR cartridge keeps practice affordable.
