Quantum Dual Taper Lock (DTL)
See all reviews | Questions (0)

Introducing the Dual Taper Lock system, available in the Quantum DTL rifle. Blackout Defense is the first in the industry to design a method of mounting the barrel and handguard that is both self-centering and resistant to axial movement.

Tapers are well known across industries to be one of the best self-centering mechanical fasteners for critical, continuous load, and loads under thermal expansion. The DTL system harnesses the power of taper locks to secure and center the barrel. 

The DTL system uses two tapers and two interlocking barrel nuts. The taper on our custom barrel extension mates with a taper on the I.D. of the first barrel nut; the second taper on the barrel profile mates with a taper on the I.D. of the second barrel nut.

This guarantees the centricity of the barrel and upper bores while stabilizing the chamber. The DTL design delivers a smoother shooting experience while prolonging barrel accuracy by providing rigidity and harmonic dampening right over the chamber.

It also provides an exceptionally rigid base for mounting the handguard that does not result in handguard deflection, while also substantially reducing POI shifts from impact and trauma to the rifle.

The barrel in the DTL system features a heavy profile and precision-machined thermal expansion rings. These rings encourage the barrel to expand in the direction of the bore rather than to deflect and shift MOA when under extreme heat.

Our Blackout Defense barrel, with our muzzle device, is capable of shooting 1MOA or better*

*Based on a 100-yd test in our facility and 77gr OTM Black Hills Ammunition

Dual Taper Lock system

The Dual Taper Lock system works in conjunction with our proprietary tapered barrel extension and tapered barrel. This provides a "push-pull" relationship ensuring bore centricity of the upper receiver and barrel.

Expansion ring cuts

Prolonged shooting creates a lot of heat, which can be the enemy of precision. Hot metal expansion becomes irregular. The thermal expansion rings featured on our DTL barrel guide the barrel to expand in the direction of the bore rather than to deflect and shift MOA.

Exceptionally rigid

Thanks to the dual taper mounting system, the proprietary handguard mount delivers extreme rigidity between the upper receiver and handguard. No handguard deflection while keeping the barrel in place when exposed to extreme impacts or trauma.

Precision lapped barrel

Our heavy profile precision lapped barrels start with Premium 416-R stainless steel bars that are gun-drilled and reamed in 5R rifling and 1:8 twist with increased cycle times and frequent tool changes for tighter tolerances across the entire production run. They are then lapped to reduce tooling marks and achieve a superior bore finish. The blanks are then fully stress relieved and precision air gauged before profiling, threading, and chambering begins.

Available in Black Nitride or cryogenically treated finishes.

Presslock™

The Quantum series lower receivers are equipped with our patented Presslock™ technology. The Linear Compression Pad ensures a tight, rattle free fitment, essentially "bedding" the upper and lower receiver together while eliminating carrier tilt.

Anti-rotation pins

Our uppers and handguards feature precision drilled pinholes for perfect monolithic-like alignment and anti-rotational rigidity.

7-side M-LOK compatible handguard

The DTL handguard features 7 sides of M-LOK compatible slots front to back. Combine that with our full length picatinny top, and your accessories can be configured exactly the way you want them.

Zero™ Short Reset Trigger

Zero pre-travel. Zero post-travel. Combined with our short and positive reset design, the Zero trigger is exceptionally smooth, crisp, and fast.

    Great rifle- some caviats

    Alfonso G

    I love this rifle, it feels nice and looks just as good- that said I have a couple thoughts.
    1. for this price it should have come with a full Ambidextrous lower, I understand that one is being created but as an early adopter I can’t stop thinking that for the same price I could have gotten a reputable rifle with this feature included.

    2. few parts are as important as the barrel, and barrel wear is happens. I was wondering when the time comes, will I be able to replace the barrel with any barrel of my choice or it will have to be a Blackout Defense barrel? (proprietary).

      Two suggestions Blackout team:

      (1) Most companies in this price range are shipping with Ambi controls; To be truly high end AR, you need to make your receiver AMBI.

      And (2): This may sound shallow, but current hand guard looks nerdy and not stylish. I just need 3-6-9 MLOKs, so you should consider milling rest of the sides with a more signature look like Radian, LMT, LWRCI.

      Thank you for your feedback. We are working on a full ambi lower with unique controls. We currently offer an ambi safety and mag release. It will take some time for us to engineer and test a unique ambi mechanism for the bolt release, and we appreciate your patience. Regarding the handguard, we are working on a second generation handguard that will launch early next year. We expect that this new generation handguard will have some unique design element in the lower 45 degree positions. We anticipate keeping at least some of the upper 45 degree positions as MLOK to accommodate operators who prefer to mount lights offset and tight to the top pic and for those who like a 45 degree position for their QD sling mount.

      No, we do not pin our gas blocks in the current version of the DTL. Our barrels are dimpled and we properly torque the gas blocks to prevent rotation.

      1. We do plan to expand our line of OSS muzzle device offerings. 2. The new ambi lowers have a few machining operations left before we send to anodize and Cerakote and bring them into inventory for assembly. 3. We do not anticipate selling the ambi lowers by themselves, but (i) as a set with our upper receiver; and/or (ii) in a builders set with our upper receiver and handguard, and/or (iii) as a set with our complete upper.

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.

      In our testing, the new Sierra 5 has demonstrated a much quieter sound profile than Sandman with .223 and 5.56 ammunition. The Sierra 5, however, is a dedicated 5.56 suppressor. If you are looking for a more versatile suppressor that you can use with other calibers and platforms, including bolt action, we would recommend the Sandman. The Sandman exhibits a good overall sound profile with .223 and 5.56 ammunition, but has a larger bore diameter and is rated for up to .300 RUM.

      Our barrels are 416R stainless steel and button rifled in 1:8, 5R. Our complete uppers and rifles with these barrels are sub-MOA guaranteed. Given our ability to achieve this accuracy with button rifling, the amount of investment needed for cut and/or cold hammer forging (upwards of $7M in investment) and our desire to keep our rifles and complete uppers relatively economical and to serve a wider audience, it was a business decision to not pursue cut rifling and/or cold hammer forging. It may be something we reconsider down the line.

  23. Question

    Zach Hansen

    Is there a reason you elected not to have a forward assist on the rifle? What is the extrusion aft of the dust cover? Is there a reason you would recommend 13.9 vs 14.5? Is there any specific companies you would consider to be your direct competitor that you outshine? I love the engineering that appears to have gone into your rifles.

  24. Question

    Jack

    With the Quantum DTL it shows a barrel length of 13.9 my state requires my rifle to be 16″ can this be pinned/welded to meet my state requirement or am I only to be able to purchase the older gen rifle at 16″

      We likewise require that our 13.9″ rifles be pinned and welded before shipping, as we are not selling SBRs at this time. Our standard 13.9″ rifle configurations come with a pinned and welded Keymo (Dead Air compatible) brake. On our “build you own” page, you must select one of the muzzle device options from the drop down menu or send us an appropriate length-muzzle device of your choosing for pinning and welding.

  25. Question

    Adam Elghriany

    I am interested in purchasing the Quantum DTL in the near future but I live in New Jersey. I see that you say that you need assurance in writing from my local dealer that the gun will be made state compliant. How would you need that provided. My local dealer has a gunsmith on staff and can do what needs to be done to bring it to state compliance. In other words how would you need it to be provided in writing?

      1. Why is the Quantum DTL only available in a 13.9″ barrel?
      2. Is 13.9″ with a 1.1″ (for the 16″ total length) muzzle device the longest barrel the DTL system will safely secure?
      3. Would you please post picture of each color scheme with an appropriate label on items that offer a color choice? For instance, on the lower/upper/handguard and builders kit there are several choices for color with no picture giving an example of that color. One company’s version of burnt bronze is not the same as another company’s version burnt bronze, etc.

      Business considerations such as inventory control and lead time impact what is made available on the site at any given time. Our Cerakote colors are depicted throughout the website on various pages.

      Another question, what would need to be modified on the DTL in order to make it NJ compliant?

      Please call your local New Jersey dealer to discuss the necessary modifications. You may also consult the guidance published by the New Jersey State Police here: https://nj.gov/njsp/firearms/firearms-faqs.shtml (FAQ #15).

      We typically request that your dealer e-mail us stating that they are capable of providing the required gunsmithing services and will perform those services in advance of transferring the rifle to you.

      We chamber our barrels in .223 WYLDE, which is a hybrid chamber that is rated for BOTH .223 and 5.56 ammunition. We do NOT offer .300BLK at this time.

      We do not sell SBRs at this time. All barrels shorter than 16.0″ are pinned and welded to an appropriate length muzzle device to exceed 16.0″ total overall length.

      We would recommend black nitride for duty use. It is exceptionally corrosion resistant with a long life.
