Blackout Defense Quantum DTL, .223 Wylde, 16" Barrel, 1- 30rd Magazine, Gray, Rifle

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*
