Quantum Mark 2
See all reviews | Questions (0)

The Quantum Mark 2 is the perfect blend of performance and aesthetics. When an aerospace company that is obsessed with design and tolerances creates an AR-style rifle from scratch, you better believe it will perform.

Every major component of the Quantum Mark 2 is manufactured in-house with painstaking attention to detail. Because of this we can ensure perfect fitment, providing the ultimate end result without regard to loose tolerances found acceptable by other manufacturers.

The entire rifle is tuned for performance. We want you to be as proud to own it as we are to make it. All you have to do is give it a try and you’ll be hooked.

The Quantum Mark 2 feels as good as it shoots. All edges are deburred by hand, and our finishing process delivers a rifle so smooth you won’t want to put it down. What you are left with is a complete rifle you’ll want to shoot all day. And that’s money well spent.

 

At this time, our rifles are not compliant in California, Connecticut, the District of Columbia, Massachusetts, New Jersey, or New York.  

We will not ship this rifle to California or Massachusetts. We will ship to Connecticut, the District of Columbia, New Jersey, and New York ONLY with advanced assurance in writing from your dealer that the rifle will be modified to be state compliant before transfer to you.  Rifle orders from these states – in addition to rifle orders from Colorado, Hawaii, Maryland, Vermont, and Washington – will ship with 10-round magazines.

Our rifle is Maryland compliant. Our barrels are heavy profile and for orders to Maryland, we laser engrave “HBAR” on the barrel before shipping.

Dead Air Silencers® KeyMount Muzzle Brake

Our 13.9" barrel Quantum Mark 2's come with a pinned and welded Dead Air Silencers muzzle brake. This makes 16" barrel length, while providing you with an excellent brake that's ready for your silencer.

Performance barrel

The Performance Series barrels start with premium 416-R stainless steel bars that are gun-drilled and reamed at standard production speeds in 5R rifling and 1:8 twist. The blanks are then fully stress relieved and precision air gauged before profiling, threading, and chambering begins.

Our barrel profile features strategically placed linear expansion rings that control the heat growth of the barrel during heavy use. These unique design features, coupled with our adherence to improved machining tolerance standards, result in straighter bores, a superior finish, and improved accuracy.

      Is this Dual Taper Lock the only difference between these two rifles Mark2 vs DTL, or will be more?
      And are you guys planning to come out with a pistol version any soon? and if yes – around what time?

      The principal difference between the two lines is our proprietary dual taper locking barrel and handguard mounting system. This system consists of two barrel nuts that mate with tapered profiles on our extension and barrel. These tapers guarantee centricity and alignment of the barrel and upper bores. They also secure the barrel and handguard in a manner that reduces barrel harmonics and prevents MOA shifts from impact. Our DTL line will also feature our 7-sided M-LOK handguard and 45/90 degree safety selector.

      Our Quantum DTL (Dual Taper Lock) is a separate rifle line that we will carry alongside the Quantum Mark 2. The Quantum DTL is launching soon. Our space grey and black anodize finishes are depicted on our website. Our other finishes, including FDE and burnt bronze, are being added to the website soon, but we also frequently depict them on our Instagram page in both studio and natural light settings.

      Yes. We chamber our barrels in .223 WYLDE, which is a hybrid chamber that is rated for BOTH .223 and 5.56 ammunition. The Wylde chamber has more room in the throat to accommodate the higher pressure of 5.56 NATO, while maintaining the improved centricity – and accompanying accuracy – of .223 Remington.

      The calculation is barrel length + muzzle length – 0.6″ (thread overlap). With a 14.5″ barrel pinned and welded to the SureFire SOCOM Muzzle Brake (2.6″), you end up at 16.6″ OAL (14.5″ + 2.6″ – 0.6″). With our shorter barrels, if we are within 0.1″ of 16.0″, we shim it to exceed 16.0″.

      Not currently, though we are looking at different possible CA-compliant configurations and would appreciate the feedback of CA residents. Do you prefer maglock or featureless? If maglock, do you have a brand preference? If featureless, what is your preferred grip? In the meantime, you can purchase a rifle and we can recommend dealers outside of CA who will convert your rifle and then ship it into CA in a compliant state.

    • Ben D

      This would be my fiorst AR, but having shot some, I’m definitely in the mag-lock camp. No featureless or fin-grip for me…Aslo, I’m not sure about having a purchase shipped to another dealer for conversion as I have no experience doing that., but thanks for the suggestion! Since you’re not doing a CA comp model, I am also considering LWRC since it comes with the Juggernaut kit- to me this seems like the best option for dealing with the locked mag. I’d also consider DD (and add the jug kit).. Hopefully when I’m ready for my second rifle, you will have one for CA. Cheers!

      Yes it is a stock item that we build for dealers and distributors. Your order will still go in the queue for fulfillment, but the lead time is usually no more than 2 weeks.

    What are the specs on the buffer spring and weight? Everything seems to be listed except that. Is it just mil spec or do you recommend a specific spring and weight for the rifle?

      Blackout Defense

      The rifle is shipped with a standard carbine-length action spring, but it is chrome silicon with a higher stiffness factor than mil-spec. The rifle also ships with a standard carbine buffer – we do this to ensure that the rifle will cycle reliably with the widest range of ammunition. We have heard from several customers, however, that H1 also functions very well.

  16. Question

    Brian Hahn

    Are Upper and lower receiver parts kits available to purchase? It looks like I can buy most parts for your rifle , except parts like the mag release, and take down pins, springs etc. Was thinking I can just kinda keep buying all the parts then build when I get them all acquired. A little easier to buy that way over time instead of the 2100 or so all at once? Thanks for any info.

    I’m not big on reviews, but after receiving this rifle ,I feel I owe it to anyone else who is interested in one of the nicest ar15s Period. This rifle is a gamechanger.
    I saw a video on YouTube by tactical consideration s, looked really good, was just looking for a good trigger. That video sold me on the Blackout defense zero trigger. After seeing the quality and performance of the trigger and charging handle, I had to get a Quantiym mark 2.
    Man I am glad I did. This rifle is as close to perfection as could be. It is soon smooth when racking the bolt, it’s amazing. It is real flat shooting with the new horizon muzzle brake. No recoil at all and it is fast, real fast. I attention to detail is crazy. Not a tool mark anywhere. You can see some of there shop on Facebook and the crazy machinery they use, unlike any others. I own a few nice ars and this is the best.
    Once these get around I believe they will or should make a huge run to the top tiers of the platform.
    Shipped very fast. Customer service is real nice and wanting to help answer any questions you may have, like I did. A must have. Thanks Blackout defense for this masterpiece. Waiting for new optic in pic.
