Extended Top Rail M-Lok | S | Krait MKII – extended optics mounting rail with 20 MOA incline

The Extended Top Rail M-Lok is an extended mounting rail designed for the Airmaks Arms Krait and Krait Lite air rifles. It provides additional mounting space for an optic and features a built-in 20 MOA incline and an integrated spirit level. The rail is made from 7075 aircraft-grade aluminium and has an overall length of 27.5 cm.

Construction and materials

The rail is manufactured from 7075 aluminium alloy, selected for its strength-to-weight ratio. The finish is black, giving a neutral, non-reflective surface. The top section features a 22mm Picatinny rail for optics, while the underside includes M-LOK slots for mounting additional accessories.

Application and use

The integrated 20 MOA incline tilts the optic slightly forward, providing additional elevation adjustment range for long-range shooting. This allows elevation corrections at greater distances without reaching the limit of the optic's internal travel. The rear spirit level enables checking for cant before the shot, improving accuracy at distance. The M-LOK slots allow mounting of accessories such as a bipod.

Integration and compatibility

This rail fits specifically the Airmaks Arms Krait MKII platform and is mounted directly onto the air rifle. The top rail uses the Picatinny standard for optics, and the lower mounting interface follows the M-LOK standard. It is compatible with the Krait and Krait Lite models.

Maintenance and lifecycle

The aluminium construction requires no specific servicing. Periodic inspection of mounting screws and contact surfaces is recommended to maintain a secure fit.
