The HK416 is a modular assault rifle designed and manufactured by Heckler & Koch. It is a direct impingement variant of the AR-15 platform, incorporating several improvements to enhance reliability and performance. The HK416 has gained widespread recognition as a high-quality and versatile rifle, used by military and law enforcement agencies around the world.
History and Development
The HK416 was developed in the early 2000s as a response to perceived reliability issues with the M4 carbine, a variant of the AR-15. Heckler & Koch designed the HK416 to address these concerns by incorporating a piston-driven system and other enhancements.
Design and Features
The HK416 shares many similarities with the AR-15 platform but features several key differences:
- Piston-driven system: Unlike the AR-15’s direct impingement system, the HK416 uses a piston-driven system that directs gas from the barrel to a separate piston, reducing carbon buildup and improving reliability.
- Improved gas regulation: The HK416’s gas regulation system is more adjustable than that of the AR-15, allowing for better performance in different conditions.
- Barrel change system: The HK416 features a quick-change barrel system that allows users to easily swap barrels for different calibers or barrel lengths.
- Modular design: The HK416 is highly modular, with interchangeable parts such as handguards, stocks, and triggers.
- Picatinny rails: The HK416 incorporates Picatinny rails on top, bottom, and sides, allowing for the attachment of various optics, accessories, and tactical equipment.

The HK416 is available in several variants, including:
- HK416A5: The standard model with a 14.5-inch barrel.

A wide range of accessories is available for the HK416, such as:
