Overview

The SilencerCo Omega 300 is a multi-caliber suppressor that has earned its place as one of the most popular rifle suppressors ever made. Introduced in 2015, it combines technology from SilencerCo's Saker and Harvester designs to produce one of the shortest and quietest multi-caliber suppressors in its class. The fully welded construction using Cobalt 6, Inconel, titanium, and 17-4 stainless steel delivers exceptional durability while maintaining a compact 7-inch profile.

What sets the Omega 300 apart is its versatility across calibers ranging from .223 Remington up to .300 Winchester Magnum, all in a package weighing just 14 ounces. The suppressor achieves impressive sound reduction with ratings of 119.5 dB on .300 BLK, 130.1 dB on 5.56mm, and 133.9 dB on 7.62mm. Using the correct front caps can reduce dB levels an additional 2-5 dB.

As an NFA-regulated item, the Omega 300 requires ATF Form 4 approval and a $200 tax stamp. The wait time typically ranges from 6-12 months. Once acquired, the ASR mounting system provides quick-attach capability across multiple hosts, and the replaceable end cap design allows users to service the suppressor without voiding the warranty.
