SILENCERCO OMEGA 300 DTM SUPPRESSOR - FULL-AUTO RATED, DIRECT THREAD, 5.56 NATO TO .300 WIN
The SilencerCo Omega 300 DTM (SU5400) is a full-auto and magnum rated .30 caliber direct thread suppressor for AR-15 carbines, hunting rifles, and precision rifles, rated from 5.56 NATO to .300 Win Mag. SilencerCo bills it as the best-selling suppressor in history. Built from 17-4 stainless steel, Cobalt 6, and Grade 9 titanium, the Omega 300 DTM weighs 12.6 oz and measures 6.98" long and 1.57" in diameter, with a black Cerakote finish.
Out of the box, the Omega 300 DTM ships with a 5/8x24 Bravo Direct Thread Mount and a .30 caliber Anchor Brake installed. SilencerCo says the Anchor Brake improves sound reduction and mitigates recoil, and it can be swapped for caliber-specific Bravo flat front caps. The rear of the suppressor uses HUB (1.375x24) threads, which SilencerCo calls its Bravo mounting system. That opens up a wide variety of thread pitches and mounting options, including the Bravo ASR Mount for quick attach and detach, the SilencerCo TOM, and third-party HUB-compatible mounts such as Dead Air KeyMo and Plan B by Q.
For barrel length, SilencerCo rates the Omega 300 DTM down to 10" on 5.56 NATO, 16" on 7.62 NATO, and 20" on .300 Win Mag. On a 16" AR with 5.56 NATO, SilencerCo measured a 131.4 dB muzzle average.
CAPITOL ARMORY'S OPINION
The Omega 300 DTM is one of the most popular .30 caliber suppressors we sell, and there's a good reason it's the best-selling rifle can out there. It's well rounded and extremely versatile, so it's just as much at home on a hunting rifle as it is on a duty rifle. Being full-auto rated means it's built for the hard use a duty gun sees, and at 12.6 oz it won't weigh down a rifle you're carrying all day in the field.
This is the silencer that redefined the standard for a 7.62 suppressor. Its Bravo mounting system went on to become the industry standard HUB pattern, so you can run SilencerCo's direct thread and ASR mounts or pick from a huge range of third-party HUB mounts. Honestly, we don't have any real negatives to point out.

What mounting system does the Omega 300 use?
The Omega 300 uses the 1.375x24 HUB mount interface, branded by SilencerCo as "Bravo". It ships with a 5/8x24 direct thread mount, and can be upgraded to ASR quick-detach, Dead Air KeyMo, or Plan B by Q for one-handed attachment and removal. The Bravo/HUB system means you're not locked into SilencerCo's ecosystem. A wide range of third-party mounts work right out of the box. If you already run ASR muzzle devices on your rifles, just purchase and install the Bravo ASR mount you're ready to go.
What calibers can it handle?
The Omega 300 is rated from .223 REM/5.56 NATO all the way up to .300 Winchester Magnum. Minimum barrel length requirements apply: 7" for .300 BLK, 10" for 5.56 NATO, 16" for 7.62 NATO, and 20" for magnum calibers. It's also worth noting that cast lead projectiles (including 22LR) are not recommended for use in any SilencerCo sealed suppressors.
What's the difference between the Omega 300 and the Scythe Ti?
These two cover different priorities. The Scythe Ti is the ultralight hunting-focused option. It weighs just 7.3 ounces thanks to its Grade 5 and 9 titanium construction, and measures 6.16 inches in length. It's also not full-auto rated. The Omega 300, by comparison, is a heavier but proven stainless and Inconel suppressor with a long track record. It runs a bit heavier at around 14 oz, but it's full-auto rated, magnum-rated, and arguably more durable under hard use. Both cover .223 Rem through .300 Win Mag territory. If minimum weight is your top priority and you're strictly running bolt guns in the field, the Scythe Ti is compelling. If you want one can that does it all, the Omega 300 is the more versatile choice.
What's the difference between the Omega 300 and the Omega 36M?
The big story with the Omega 36M is modularity and expanded caliber range. The Omega 36M is a two-piece modular design. The front section can be removed for a shorter, lighter configuration and it's compatible with everything from 9mm up to .338 Lapua. That makes it a genuine multi-role suppressor for someone who wants to run one can across pistols, subguns, and magnum rifles. In its long configuration on rifles, the Omega 36M delivers comparable performance to the Omega 300. One major difference is that it uses the Charlie mounting system rather than the Bravo system the Omega 300 uses, so your mounting systems won't cross over between the two. The Omega 300 is the tighter, simpler, lighter package optimized specifically for rifle use. The Omega 36M is the better pick if you want pistol/rifle crossover and expanded caliber options in one suppressor.
Is the Omega 300 HUB compatible?
Yes. The Omega was HUB-compatible before everybody else was. SilencerCo's Bravo mounting ecosystem was adapted by other companies and labeled as "HUB". It ships with a 5/8x24 direct thread mount installed, but the HUB interface lets you swap to ASR, KeyMo, Plan B by Q, or virtually any other popular mounting system without sending the can anywhere. The included tools make the swap straightforward at home.
Is it good for hunting?
Absolutely. In fact, it's one of the best hunting suppressors on the market. If sound reduction is your primary concern, the Omega 300 is the answer for precision and hunting applications. It's short enough in direct thread configuration (6.09" without the brake) to keep your rifle handy in a blind or on a stalk, light enough not to ruin your rifle's balance, and quiet enough to protect your hearing shot after shot without plugs. The broad caliber range is a bonus. One can covers your deer rifle, your hog gun, and your varmint rig. If weight is the absolute deciding factor and you're running bolt guns only, the Scythe Ti nudges ahead. But for most hunters who want durability, versatility, and outstanding performance, the Omega 300 is hard to beat.
What's that funny-looking thing on the front? (The Anchor Brake)
That's the Anchor Brake, and it's actually doing double duty. The ported brake design redirects gas to reduce felt recoil and muzzle rise while also improving sound reduction compared to a flat end cap. Depending on the caliber, it can reduce felt recoil noticeably, especially on bigger cartridges like .300 Win Mag. If you'd rather run without it for a slimmer profile or to shave an inch of overall length, the Omega 300 can be used with the SilencerCo Bravo Front Cap and you're good to go.
