Dead Air Sierra 5 Xeno -- SIERRA5 Xeno – DA121

Per Dead Air: The all-new 5.56 silencer from Dead Air Silencers. From the beginning, our mission has been to give No Quarter in design, performance, and technology. The Sierra-5 stands true to that mission by giving you everything you want out of a dedicated 5.56 silencer.

This is a hard-use silencer. We are not cutting costs or decreasing lifespan by using stainless steel baffles. We are not sacrificing durability in search of saving a few ounces. The Sierra-5 is full-auto rated with no barrel length restrictions. Love or hate the knurling, it’s function over form, directly inline with our goal when developing the Sierra-5. Frankly, if you don’t get the Sierra-5 red hot each time you shoot it we might be offended.

Built for professional use, it offers the perfect balance of overall sound and flash suppression while maintaining a compact footprint and minimal weight. By utilizing HUB compatible (1.375-24”) mounting adapters, it can be configured to the end user’s specific needs and is available out of the box with our Xeno mounting system.

Featuring the proven winning combination of welded Stellite® baffles wrapped in a stainless outer tube, Sierra-5 is the last 5.56 suppressor you’ll need.

The included flash hider front cap aids in excellent visual signature reduction.

Interchangeable front caps: The Sierra-5 is compatible with all of our R-Series front caps, including our E-Brake.

Fully-welded construction: All Stellite® baffles and full penetration laser welding ensures a robust and solid monolithic core structure. Then welded to the outer tube for additional strength and durability.

Mounting modularity: The Sierra-5 KM ships with the complete Xeno system (1/2-28 Xeno flash hider and a Xeno adapater).). But thanks to the 1.375-28″ HUB socket you can change your mind without regret.

The Sierra-5 features a small hole drilled through the blast chamber making it possible to pin & weld your adapter or insert to the suppressor.

The Sierra-5 is optimized specifically for high-performance out of the 5.56 platform in sound and flash suppression, while maintaining a low blowback, short pressure impulse.

This is a NFA item and all federal and state laws apply. It must be shipped to buyer's FFL/SOT, which transfer involves no ATF fees. But, the transfer from buyer's FFL/SOT to buyer will involve a $200 tax stamp which buyer is responsible to pay. The transfer to buyer's FFL/SOT will be done after payment in full. Refunds will NOT be given due to poor performance by ATF. Buyers of NFA items should be aware that ATF approval is out of our control and that no NFA item can be shipped until the ATF approves the transfer of the item, but it has been taking only a day or 2 lately.
