Where Science and manufacturing meet
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 magic of the Dual Taper Lock
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.

The DTL is a 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. Prolonged shooting creates a lot of heat, which can be the enemy of precision. 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.

Precision and durability built-in
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 barrels start with Premium 416-R stainless steel bars that are gun-drilled and reamed in 5R rifling 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.

Anti-rotation pins
Our uppers and handguards feature precision drilled pinholes for perfect monolithic-like alignment and anti-rotational rigidity.
Blackout Defense Bolt Carrier group
Our carrier is manufactured from 8620 steel, while our shot-peened bolt is made from either 9310 or carpenter 158. The bolts are batch high pressure tested and individually magnetic particle inspected after heat-treat to ensure no microcracks.
