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*

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.
