Blackout Defense Dual Taper Lock .223 Wylde Complete AR15 Upper

You’re well on your way to a better build with the Blackout Defense 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.

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 their 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 them. The dust cover is fully contained within the upper receiver. They 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, they’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

Their handguard brings the full package together with its monolithic-like style when paired with their upper. Like to accessorize? Their handguard gives you five sides of M-LOK compatible mounting slots with a full-length Picatinny top rail. The hand deburring process they put their products through ensures a smooth finish throughout. And for style-conscious people, their barrel nut is hidden to provide an even cleaner look.

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 begin. Their 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 their adherence to improved machining tolerance standards, result in straighter bores, a superior finish, and improved accuracy. The gas system for the 13.9" & 14.5" barrels is mid-length. 

Bolt Carrier Group

The Blackout Defense bolt carrier is manufactured from 8620 steel, while their 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.
