Custom Build .223 Wylde Complete Upper
$1,081.01
You’re well on your way to a better build with the Blackout Defense Dual Taper Lock (DTL) complete upper. The upper receiver and handguard are precision machined to achieve perfect alignment, giving a monolithic-like appearance. And with the alignment pins, you get a boost of structural integrity as well.
Dual Taper Lock system
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.
Upper Receiver
The upper receiver is machined from Aerospace Grade Aluminum with enhanced walls for greater rigidity and structural integrity – all while keeping a low profile. It features two anti-rotation holes that align precisely with our handguard. What you’re left with is a monolithic-like style and design with an extremely robust upper/handguard combination.
The dust cover often goes unnoticed in an AR-15. Not to us. The dust cover is fully contained within the upper receiver. We don’t rely on a C-clip to keep everything in place. Instead, the dust cover hinge pin is held in place by the barrel nut, ensuring nothing comes loose during operation. Due to the variation of dust cover manufacturers and their loose tolerances, we’ve machined a very thin locking groove in the upper receiver. This allows the ball detent of the dust cover to “cut” its own channel in the upper receiver, ensuring a positive, audible lock up and exact alignment.
Handguard
Our handguard brings the full package together with its monolithic-like style when paired with our upper. Like to accessorize? Our DTL handguard gives you seven sides of M-LOK compatible mounting slots with a full-length Picatinny top rail. The hand deburring process we put our products through ensures a smooth finish throughout. And for style-conscious people, our barrel nut is hidden to provide an even cleaner look.
Barrel
Our cryogenically treated 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 begin.
Our barrel profile features strategically placed linear expansion rings that control the heat growth of the barrel during heavy use. These unique design features, coupled with our adherence to improved machining tolerance standards, result in straighter bores, a superior finish, and improved accuracy.
The gas system for our 13.9″, 14.5″, and 16″ barrels is mid-length.
Bolt Carrier Group
The Blackout Defense bolt 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.
Charging Handle
The ambidextrous design of the Stryker charging handle allows for multiple ways of use, no matter your shooting side or position.
- Reinforced in critical areas
- Monolithic-like appearance between upper and handguard
- Alignment pins between upper and handguard

It’s awesome that Blackout allows us to customize an upper to this degree. The machining and cerakote on my 13.9″ are flawless, and everything feels rock solid. I haven’t seriously tested group sizes yet, but initial results (from shooting steel at 200 and 300 yards) are very promising. Buy with confidence!
Aaron –
What is the handguard length for the 16in barrel. I would prefer a 13 inch handguard
Blackout Defense –
We can accommodate that. Typically we install a 15″ handguard with our 16″ barrel. If you would like a 13″ handguard instead, leave that note in the order comments at checkout – those comments go directly to our gunsmithing department – and they will assemble it with our 13″ handguard. You are welcome to then email customerservice@blackoutdefense.com or call us at 480-781-0573 to confirm.

Nowhere does it say what it’s chambered in. Unless I’m overlooking it. Is it assumed this is chambered in .223 wylde? Bc that’s what I want.
Blackout Defense –
It is chambered in .223 Wylde.
Brim –
It says The gas system for the 13.9″and 14.5″ barrels is mid-length. What is the 16”? I’m going to be sending a gas block to be assembled with purchase and want to ensure I order the correct gas block and tube. Thanks.
Blackout Defense –
Our 16″ barrels are also machined with a mid-length gas system.
Danny –
Are there any piston options?
Blackout Defense –
No. All direct impingement.

Any possible offering in NRA service rifle (competition legal) with cryo-stainless DTL barrel? Maybe 24inch Varminter?

Blackout Defense –
It is not on our current project list but with enough demand that is something we would consider.

Any possible offering in NRA service rifle (competition legal) with cryo-stainless DTL barrel? Maybe 24inch Varminter?
Blackout Defense –
That is not planned at this time.
Joshua –
Do you guys offer any other calibers for barrels other than .223.
Also, will any “normal” barrel fit into your receiver or just your barrels?
wagnerfrank6596 –
Yes I acquired a dtl barrel but I don’t have the locking nuts was wondering if I could purchase them please let me know yes sir no they’re not available sincerely Frank
Blackout Defense –
Please contact us at customerservice@blackoutdefense.com or 480-781-0573.
Vladimir –
Will this upper work with Franklin armory M4 BLR lower?
Nicholas –
Are the uppers Gen 2 or they’ll be available soon.
Blackout Defense –
The uppers available on our site are the latest and greatest. We do not sell our legacy designs.
Blackout Defense –
Our upper is compatible with any mil-spec lower receiver. The Franklin Armory M4 BLR receiver appears to be a forged mil-spec receiver.
Chris –
Are the barrels button rifled?
Also how do the linear expansion rings differ from fluting regarding thermal expansion?
Blackout Defense –
Yes our barrels are button rifled. Fluting facilitates heat dissipation by way of increased surface area, but is not designed to directionally impact thermal expansion.
RJ –
Any possibility to expand barrel length offerings such as an 11.5″ or 12″?
Blackout Defense –
Yes, we are working on it!
Escamo joe –
Will yall be releasing a 6mm ARC and 300 AAC Blackout anytime soon?
Blackout Defense –
Yes. .300 Blackout is going live within days and 6ARC will be later this year.
Kyle –
Would you add an option to laser engrave HBAR on barrels so that we can have them in MD? Thanks
