Magpul’s M-Lok mounting system just received a serious endorsement from Colt Canada with their new MRR or Modular Railed Rifle. Designed for land Colt military and police contracts, this is one of the first guns by a major manufacturer to select M-Lok over other rail systems.
While Picatinny rails are dropping off in favor of M-Lok and KeyMod, neither of the two newer mounting systems have established a firm lead over the other, and both have a lot of manufacturer and aftermarket support, until now. The decision to select M-Lok was based on feedback from law enforcement and military customers.
Even though it’s not tied to any specific contract the MMR will have an influence on what system other manufacturers chose to use with their patrol and duty carbines, which will, in turn, affect the commercial market.
Of course, the only way to know if one mounting system has achieved complete success is if it is selected as a standard by the U.S. military, and even then neither system will completely die off; both have their fans and established user bases.
In addition to the new rail system, the Colt MMR represents a step forward over the IUR, or Integrated Upper Receiver, Colt Canada’s current flagship AR-15-style carbine. Apart from using M-Lok instead of Picatinny, the biggest difference is the lost weight, reports Calibre.
“The new MRR [weighs] almost a full 3/4 of a pound less than the outgoing IUR rifles when fitted with the same heavy-profile barrel.” And the IUR wasn’t particularly heavy in the first place, with the 16-inch model weighing in at 7.45 pounds. Full specifications will be revealed at SHOT Show 2016.
Other new features include a full spread of Magpul accessories, including the magazines, pistol grip, stock, foregrip and folding backup iron sights. The MMR also sports a complete Cerakote finish, including the barrel, instead of traditional anodized and parkerized finishes. One thing that hasn’t changed is the use of Colt’s ported flash hider.
The MMR also has ambidextrous controls including the magazine release and selector levers and is expected to be launched in several configurations from PDW-style compact carbines to full-size DMR rifles with fixed Magpul rifle stocks and rifle-length barrel systems and extended handguards.
Colt Canada is showing the kind of adaptability and flexibility that Colt of the U.S. needs to have. In recent years, Colt has lagged behind while other companies took over their markets in all sectors, from military to commercial and law enforcement markets.
The quality of Colt rifles has not diminished, but the quality of their competition has improved, and the rest of the manufacturing community has been hard at work finding new standards that offer more to users that what Cold does today. If a Colt rifle like the MMR was offered in the stateside it would go a long way to restoring Colt as one of leading movers in the AR market.
