Blackout Defense Complete Dual Taper Lock .223 Wylde Upper Receiver Group Slick Side 13.9in Mid Black

Blackout Defense Complete Dual Taper Lock .223 Wylde Upper Receiver Group Slick Side 13.9in Mid Black. 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 their 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 their handguard. What youre 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. They dont 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 weve 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 DTL handguard gives you seven 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. Their 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. 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. 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.
