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 main barrel nut is also compatible with MILSPEC barrels by simply reversing it. 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*

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.

The main barrel nut is also compatible with MILSPEC barrels by simply reversing it.

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.

    The nicest, Bad A** rifle I have ever seen. It has the performance to back up its looks too! I personally shot a ,43 MOA! Even with 12 year old federal LC 55 grain ammo it hollowed out the bullseye at 100 yards. Tore up clay pigeons laying on the ground at 200 yards. I am proud to own one of Blackout Defense’s eariler models. I can only imagine how much MORE accurate the cryo barrel is. An awesome company, top notch customer service, products, and dont even get me started on those triggers! I am very pleased with my purchase, well worth the money and the wait. Hurry and get your build started today!

    Best Rifle on the market bar none

    Wolfgang Schulthess

    This is by far and away the best rifle on the market and it isn’t even close. The quality cannot be matched. It feels absolutely amazing. The weight is perfect while also feeling indestructible. Their customer service is also unmatched. They are unbelievably helpful, patient, kind, and knowledgable. You will not regret purchasing from them. Their rifles are on the pricey side, but once you shoot it you will know you got a screaming deal on it.

    Exceeded expectations

    Kai

    Finally took delivery last Friday, and everyone at the store wanted to hold it and check it out – exceptional build quality. I am extremely happy with the build. If you’re on the fence about purchasing one – don’t be. It’s well worth the wait + money. Also, shoutout to the Blackout Defense team; great communication during the whole process!

    An Outstanding Weapon System

    I purchased a QUANTUM DUAL TAPER LOCK (DTL) a month or so back and performed a 1000 round burn down through it with ZERO jams or issues. Outstanding reliability, innovation and customer service, bravo Blackout Defense!

    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!!!
