One of the most iconic names in the sound suppressor business is Utah’s SilencerCo, and the company's Omega 300 suppressor, added to SilencerCo’s product line in 2015, exceeded the manufacturer’s sales expectations by selling more than 5,000 in its first year. The Omega 300 suppressor combines technology from the Saker and Harvester designs to produce what the company claims is one of the shortest and quietest suppressors in the industry. The Omega is designed for ammo ranging from the small 5.7 mm to the potent .300 Win. Mag. The suppressor has an overall length of 7.09 inches, a diameter of 1.56 inches, and a weight of only 14 ounces. The strength comes from the material from which it is made: Titanium, Stellite and stainless steel. It is not cheap, with an MSRP of $1,130, but as the old saying goes, you get what you pay for.

According to SilencerCo, its Omega suppressor has a rating of 119 dB with .300 BLK., 133 dB with a 7.62 NATO and 130 decibels with 5.56 NATO ammunition. Also, the suppressor is full-auto rated, making it an all-around/all-purpose sound suppressor.

SilencerCo’s proprietary SpecWar ASR muzzle brake facilitates rapid attachment.

SilencerCo offers different mounting apparatuses for the Omega. End caps are available in both .308 as well as .223 diameter. You can fire a 5.56 mm (.223 Rem.) projectile through the 7.62 NATO-caliber end cap with only a slight increase in report. The rearward end cap is removable. Caps are offered in direct-thread (58x24 and 12x28) end caps as well as the quick-detachable ASR (Active Spring Retention) rear mount. The quick-detach model uses the SpecWar ASR muzzle brake or flash suppressor. The use of the front end cap (or anchor brake) is purposefully designed as an enhancement. When most suppressors fail, it is usually due to a baffle strike on the end of the suppressor. By having the end cap, the last baffle in the Omega is not a fixed baffle but a removable piece that can be replaced by the user, rather than having to be boxed up and shipped back to SilencerCo.

(l.) For those who wish to attach the Omega directly to their barrel, a direct-thread attachment can be exchanged for the ASR mount. (r.) Replaceable end caps allow rapid replacement should a baffle strike occur.

The Omega is designed for 5.56 mm-chambered barrels as short as 10 inches. The Omega will accept up to a 16-inch 7.62 NATO barrel and up to a 20-inch .300 Win. Mag. barrel. According to SilencerCo, the anchor brake on the Omega is responsible for the reduction of the felt recoil of the 7.62 NATO cartridge down to that of a .243 Win. I tested this suppressor on a Noreen Firearms BN36 chambered in .300 Win. Mag. and the combination of noise reduction and recoil reduction made the powerful rifle a pleasure to shoot. The Omega was also tested on a 16-inch .300 BLK LMT MRP as well as an Aero Precision 16-inch 7.62 NATO rifle. Both displayed a reduction in recoil as well as excellent suppression. The anchor brake may be removed if the end user wishes for the shorter (6-inch) configuration of the Omega suppressor with direct-thread attachment as opposed to the 7.5-inch length including the ASR mount. Due to the titanium and Stellite construction, the Omega weighs only 14 ounces without the ASR Mount and anchor brake.

A spanner wrench for the ASR mount and an end-cap wrench are included.

The Omega package comes with the sound suppressor itself and .308 and .223 end caps. It also ships with the ASR brake, as well as the 58x24-inch direct-thread adapter. Two wrenches are provided. One takes care of the end caps and the other, which is a spanner wrench, is used on the ASR mount. Additionally, the kit comes with a protective carrying case. According to SilencerCo, the Omega does not require disassembly for cleaning due to its being used with a centerfire rifle cartridge. However, the company does not recommend firing lead projectiles, fearing these will fill the suppressor with lead vapor and deposits.

If you are looking for one of the most advanced sound suppressors in the industry today, you need not look further than the SilencerCo Omega. Be sure your firearm fits within the barrel-length and caliber specifications. This suppressor’s capabilities and design make it ideal for any rifle within those specs, and an excellent all-around choice.
