The Acheron KWS Rail System for the SG 55x rifle family has been engineered to provide a stable platform for the attachment of accessories. In comparison to conventional handguards, the Acheron KWS Rail System connects to the host weapon without any wiggle. This enables the use of rail-mounted nightvision and laser aiming devices without point-of-impact shift caused by handguard movement. This upgrade adapts these rifles to modern requirements and greatly enhances their combat value.
The top rail complies with both the NATO standard STANAG 4694 and the American standard MIL-STD-1913.
M-LOK slots facilitate the attachment of accessories like weaponlights or foregrips and allow for excellent air circulation.
Machined from high-strength aluminium, the KWS Rail system is both strong and lightweight. A hard coat anodized finish provides excellent resistance to wear and corrosion.
