HOME COMPANY CATALOGUE COURSES SHOP COLT CANADA NEWS / MEDIA CONTACT US // Member of CZ GROUP MODULAR RAIL RIFLE The MRR combines the battle proven Colt Canada C8 Carbine core with the M-LOK™ Rail Attachment System. The MRR Upper Receiver has a monolithic top rail with side and bottom rail positions now implementing the Magpul M-LOK™ modular locking accessory mounting system. The sturdy monolithic upper receiver provides ample rail space for various optics and is fitted with a Colt Canada free floating, cold hammer forged, chrome lined barrel which increases barrel service life significantly when compared to non-chrome lined barrels of similar firearms. The implementation of the M-LOK™ system allows the operator to add only the rails or accessories required for the given mission, thus reducing the weight burden on the operator. This system has reduced weapon weights by up to half a pound with the weight savings predominantly in the forestock area of the weapon. This improves the weapon’s maneuverability and overall weight distribution.
