Mk 13 rifle

The MK 13 rifle is made using the Accuracy International Chassis System (AICS) version 2.0 mated to a long action Remington 700 receiver.

The rifle has a cheekpiece design that adjusts sideways and for height for optimal cheek position when using night vision equipment or telescopic sights with large objective lenses.

Sling attachment points are mounted on each side of the rifle, so it can be carried flat against the back and used comfortably by left- and right-handed users.

A front attachment point is situated below the fore-end and can be used to anchor a target-style sling or replaced by an adapter for a Harris bipod.
