Operators Safety & Instruction Manual

Semi-Automatic Modular Rail Rifle Overview

Diemaco, lightweight, semi-automatic, Modular Rail Rifle (MRR) firearms feature a muzzle compensator,

free floating cold hammer forged barrel, and multi-position Magpul MOE buttstock and pistol grip. Firearm

configurations include models with 18.6 inch, 16 inch, and 11.6 inch barrel lengths. Both the 16 inch and

11.6 inch configurations utilize Canadian Forces specification chrome lined barrels for increased longevity

while the 18.6 inch configuration utilizes an un-lined barrel for increased accuracy. All actions are gas

operated, firing from the closed bolt.

Your MRR comes with an Integrated Upper Receiver (IUR) comprised of a monolithic top rail with the side

and bottom rail positions implementing the Magpul M-LOK modular locking accessory mounting system.

This allows for the perfect alignment of sighting devices and the mounting of a wide range of accessories.

Please make sure you read the instructions for any sights or accessories that you choose to utilize and

familiarize yourself with their individual safety and installation instructions.

For your safety and for the safety of others, whether you are an experienced shooter, or have never handled

a firearm before, we urge you to read this entire instruction manual before handling the firearm.
