Made from Grade 5 titanium and 17-4 stainless steel, the HUXWRX HX-QD 556 Ti is a lightweight 5.56 rifle suppressor, at just 13.1 oz and 6.67”. The HX-QD 556 Ti features patented OSS Flow-Through technology to reduce back pressure and toxic gas blowback into your face. This groundbreaking engineering has led some customers to ask: what is Flow-Through technology? This system utilizes cones and coils to redirect gas, instead of traditional baffles. The result is incredibly low back pressure and significant decibel reduction. The OSS tech is game-changing, securing its place on our top 5 list for the second year in a row. The incredible reduction of back pressure puts this suppressor as one of the best 5.56 suppressors for your short-barreled rifle (SBR). The HX-QD 556 Ti’s unique internal geometry also reduces recoil and muzzle flash and provides excellent sound suppression, especially at the shooter’s ear on an AR-15 or a similar modern sporting rifle (MSR).


HUXWRX’s QD muzzle devices interface with the HX-QD’s Torque Lock mounting system providing two key benefits to the shooter: assurance that your silencer is firmly affixed to your host, while also preventing the muzzle device from getting carbon locked to the silencer.


If you're running drills, competing in matches, or part of a professional unit; the high-tech HX-QD 556 Ti is designed with you in mind. The revolutionary OSS Flow-Through design allows your gun to operate reliably without the need for in-depth tuning, keeping you on the range instead of trying to make repairs. It’s top-of-the-line and will serve you well on any AR-15/M-16, including full-auto use, or any other carbine or rifle in .223/5.56.

The CGS Helios QD Ti is quite possibly the best suppressor for 5.56 and 300 blk. With a perfect 5 out 5 star rating, customers have called it “Incredibly light and sounds great. 11/10 would buy again” and “The best. Period.” This compact suppressor is just 7.2” and is constructed with an advanced DMLS (direct metal laser sintering) manufacturing technique, the Helios QD Ti has internal structures that are an engineering marvel, far evolved beyond traditional manufacturing. The result is an efficient, quiet, durable, lightweight silencer that can be used on everything from .223/5.56 up to .300 Norma Magnum. Is titanium better than stainless steel for a suppressor? The QD Ti is constructed of sintered titanium and weighs 9.6 ounces (without a mount), and because titanium can achieve similar strength as steel (at only a fraction of the weight), the CGS QD silencer is durable and also the lightest weight suppressor in the Silencer Shop Top 5 (it even weighs less than some K sized cans).


With its generous bore diameter and solid construction, the Helios QD Ti is also rated for .30 caliber cartridges, while providing low back pressure on an AR-15/M-16 platform. The Helios is a standout choice for AR-style rifles as well as precision bolt guns; it provides outstanding suppression while preserving the maneuverability of the rifle.


CGS Suppressors ships the Helios QD Ti as a complete kit with multiple mounts and adapters in a hard-sided case. You’ll be ready to use the Helios QD Ti on both .223/5.56 and .30 caliber hosts right out of the box. The lightweight design coupled with the versatility of a larger bore makes the Helios QD Ti great at the flat range or hiking to your hunting site.

The YHM Turbo K V2 is a smaller version of the Turbo T2 (#2 on our list above). The Turbo K is shorter, lighter, and a bit more maneuverable; which is achieved by reducing a few baffles. Silencer shop customers tout the Turbo K as having “Excellent performance. Lightweight. Robust.” giving it 4.8 out of 5 stars. It shares all of the same features, construction, and caliber/barrel length ratings as its bigger sibling, in a shortened package. 


Like the Turbo T2, the Turbo K (V2) is a fantastic silencer choice for dedicated AR-15/M-16 use. At 4.9” it’s ideal on a patrol rifle, tactical rifle, or hunting rifle as it’s very compact and mobile weighing only 10.5oz. This suppressor will reduce harsh muzzle blast and concussion and bring down the Db’s to a more comfortable level. If a short size is the primary quality you’re looking for, the Turbo K has you covered.
