Update on FightLite MXR Full Auto/Pistol/Rifle, MCR | SHOT 2017

Melbourne, FL based Fight Lite Industries is the current company that was formally known as Ares Defense until it was renamed. Our own Pete M. published the press release showing the MXR’s introduction before SHOT, and we got a further in-depth look at the MXR while at the actual booth on the floor. The idea of the MXR came from an operational requirement from several LE agencies in Europe following the attacks on the Bataclan Theater in Paris in November of 2015. According to the designer, officers armed with handguns were severely outgunned by the AKM armed terrorists. Similar to why Britain’s London Met CT unit is adopting 5.56x45mm Sig MCXs, is to combat the threat levels that opponents are reaching within Europe. Having a pistol caliber carbine in an officers patrol car would offer a much more significant advantage over a duty handgun when dealing with Bataclan-like terrorist attacks, especially when it takes the same magazines and ammunition. Ballistics of 5.56x45mm/.300 BLK versus a 9x19mm round against body armor aside, a pistol caliber carbine certainly solves the logistical issue.

This was one of the driving concepts behind the MXR, in addition to breaking into the pistol caliber carbine market in the United States. The company isn’t going to be doing this with the full auto variant but instead with the pistol variant equipped with a stabilizing brace, or in the rifle variant with a 16″ legal barrel, and a telescoping AR stock on a buffer tube. Conversion between calibers can be done through the magazine well, and the barrel, choosing from a variety of manufacturers for the magazine. These include Sig Sauer, Beretta, Glock, CZ, among others. Calibers currently range from .22 LR, 9x19mm, and .45 ACP, but should increase if demand does as well. Converting or changing barrels is extremely simple, using a sort of round barrel nut at the edge of the forend to unlock the barrel and pull it out. Charging handle is on the left side, while the magazine well is on the right, and these options are not ambidextrous. Keymod slots align the three and nine o’clock sections of the forward rails, while picatinny interfaces align the twelve and six o’clock portions.

And of course the companies MCR, a carry over from the previous belt/magazine fed upper receiver was reintroduced, with some different iterations than the previous Shrike light machine gun/rifle(within the U.S. civilian market). The MCR is being offered in a number of different barrel configurations with both fluted, normal, suppressed, 16″ and 12″(SBR or separate receiver).

    Solving a logistical problem does not actually solve a tactical problem. The police responding to the Bataclan attack were outgunned by terrorists with AKs. Well, providing them with a pistol caliber sub-gun is weak sauce.

    • Vhyrus

      Assuming no body armor, a compact sub gun is potentially better at short ranges and in tight hallways than a full size ak.

        “The police responding to the Bataclan attack were outgunned by terrorists with AKs”
        “for these guys in 1980.”
        are you comparing the first units who arrived on the scenes to contain the menace in a defensive role and in an urban combat situation to an offensive action lead by an heavily equiped unit(breaching charges,flashbangs,kelvar vest) in a Close Quarter Combat situation ?

        • BattleshipGrey

          I’m basing my statement on the only photos I’ve seen of the entry team, of which all members seem to be carrying MP5s, and the fact that all of the terrorists (save 1) were killed. I haven’t seen anything suggesting entry team deaths.

  • Beardedrambler

    Msrp for the pistol version?

    • Tim Barrera

      $700 with poly lower, little more with billlet – per brownells youtube vid at shot show.

  • Joe

    How about an MCR enlarged for 7.62 NATO?
    I like the caliber conversion options, I just hope MSRP is significantly lower than their belt fed uppers.

    • Squirreltakular

      Oh man, yes. I would buy that in a hearbeat.

  • JSmath

    Not really convinced the MXC is going to be worth what they’ll charge for it (considering price of MCR upper vs other AR15 uppers).

    Miles, the article could use a once over. Many guns have used barrel nuts like the MCX does – Uzi comed to mind but I know I’ve seen others. Additionally, the mag release is on the right, not the mag well, and it nor the charging handle are options but features (ambi or not).

    Had to edit bc of course my phone doesn’t recognize Miles as a name.

  • Disgruntled

    Quit hyping up fight lite. They can’t manufacture enough of the guns they design. The ares scr rifle has seen supply stock outs for the past year. They have awful customer service that can’t answer when their stock will be replenished.

  • Tim Barrera

    What’s with all the hate? Everyones doing pistol cal carbines now…. I thought it was a good article, informative and detailed. The French requested a pistol caliber carbine, so that was what Fightlite produced. MSRP on the MXR is set to be about $700 with poly lower. Little more with billet lower. That’s right in line with the scorpion and gives ar parts compatibility. And cheaper than sig, kalashnilov usa and most other pistol cal ar companies…

    You wanna complain about production? Go complain to keltec first! My local shop has 4 SCRs right now. They are out there.

    Call me a fan boys if you want but I’m super excited about this. Quick caliber change, various pistol mag compatability, quick barrel change, side charging for good suppression containment…. only thing is I hope like heck that the law side folder mech works with it… then it’d be perfection!

    • John Sabatini

      That’s the first time I’ve heard msrp mentioned. At that price this could be a great option

  • RSG

    I wish the belt fed upper was more reasonably priced. With a slide fire stock, would be a perfect porch gun. Excellent for driveway denial.
