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.

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, 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.

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.

Heavy profile 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.

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.

    As a 30+ year engineer in DOD Space & Intelligence, I can clearly see the innovation and attention to quality/reliability that went into the Quantum DTL rifle. Plus the multi tone clear anodized/burnt bronze cerakote is simply stunning!! I will be ordering one soon and since I’m a resident of Chandler, I might just stop by your office and place the order in person (if that’s allowed). Keep up the good work!!!

  3. 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.

    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.

      We are not currently in production for a 16″ DTL barrel. Our mills and lathes are busy machining 13.9″ and 14.5″ DTL barrels and our forthcoming Keymo muzzle devices. We do plan to offer a 16″ DTL barrel option for our rifles and complete uppers in the future, however. In the meantime, we do offer pinning and welding to qualify our shorter barrels as 16.0″+. Subscribing to our newsletter and following our Instagram is the best way to stay up-to-date on the latest products in production and development.

  9. 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.

      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.

      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.

      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.
