What Does “30 Cal Suppressor” Mean?
“30 cal” refers to any suppressor with a .30 caliber (7.62mm) bore — the most versatile bore size in the industry. A 30 cal suppressor is rated for .308 Winchester, 7.62 NATO, 300 Blackout, 300 Win Mag, 300 Norma, 300 PRC, and in most cases 6.5mm cartridges like 6.5 Creedmoor and 6.5 PRC as well. One suppressor covers your entire rifle lineup.
Energetic Armament makes four 30 cal suppressors — each purpose-built for a different shooter and use case. Here’s how to choose.

VOX-S — Best 30 Cal Suppressor for Hard Use & Full-Auto
The VOX-S is Energetic Armament’s flagship full-size 30 cal suppressor, built from C300 Maraging nickel-cobalt superalloy — the first silencer manufacturer to apply this aerospace material to a suppressor. With a tensile yield strength of over 270ksi — more than double 17-4 stainless and stronger than titanium at temperature — the VOX-S is engineered for the most demanding full-auto use cases without the weight penalty of conventional materials.
At 12.9oz and 5.9 inches with a wiped end cap standard, the VOX-S delivers maximum sound attenuation across the full 30 cal spectrum. Compatible with all industry-standard 1.375×24 HUB quick-disconnect mounts.
Best for: Full-auto rated rifles, hard use, duty applications, shooters who want maximum sound attenuation in a full-size package.
VOX-K2 — Best Compact 30 Cal Suppressor for Short Barrels
The VOX-K2 is the compact ‘kurtz’ configuration of the VOX platform — the same C300 Maraging superalloy core in a 4.9 inch, 10.4oz package. At 60% better weight efficiency at the muzzle and 54% greater length efficiency than the legacy VOX-K, the K2 sets a new benchmark for compact 30 cal suppressors without sacrificing the full-auto rating.
Purpose-built for short-barreled rifles, pistol-caliber carbines, and any host where muzzle weight and overall length are mission-critical. Wiped end cap standard. Flash hider end caps available in 7.62mm and 5.56mm.
Best for: Short-barreled rifles, compact builds – shooters who prioritize size and weight without giving up full-auto capability.
Peak 30 — Precision Engineered 30 Cal Suppressor for Dynamic Rifle Hosts
The Peak 30 is Energetic Armament’s versatile 30 cal rifle suppressor — a 5-baffle laser-welded 17-4 H900 stainless steel core at 11.9oz, built for shooters who run multiple calibers from a single suppressor. Rated for everything from 5.56 NATO to .308 Winchester, 6.5 Creedmoor, 6.5 PRC, 300 Blackout, 300 Win Mag, and more — with no barrel length restrictions under 1,000°F.
The same end cap mount pattern as the VOX, FEROX and Sonus lines means universal accessory interchangeability across the EA lineup. Black nitride finish throughout for extreme surface hardness and corrosion resistance. Backed by the patented Serial ID Ring.
Best for: Multi-caliber rifle owners, hunting applications, shooters who want broad compatibility at an accessible price point.
LUX 7.62mm — Best 30 Cal Suppressor for Precision Rifle
The LUX 7.62mm is Energetic Armament’s lightweight precision titanium 30 cal suppressor — welded to AWS standards from US-origin DFARS compliant 6Al-4V Grade 5 titanium throughout. At 9.84oz with direct thread mount, the LUX is the lightest 30 cal suppressor in the EA lineup and the choice for bolt-action and semi-automatic precision rifle shooters where weight efficiency is paramount.
Internal surfaces are coated with a proprietary boron nitride process for wear and fouling resistance. External Diamond-Like Carbon (DLC) finish provides outstanding surface protection in a dark gray profile. Rated for all cartridges with 7.62mm or smaller projectiles — .308 WIN, 300 WM, 6.5 Creedmoor, 6.5 PRC, 300 BLK, 300 PRC, 300 Norma and more.
Best for: Precision bolt-action rifles, long-range shooting, hunters, shooters who prioritize minimum weight on a precision platform.
Which 30 Cal Suppressor Should You Choose?
Choose the VOX-S if you run a full-auto or hard-use rifle and want maximum sound attenuation with a full-size suppressor that won’t fail under sustained fire.
Choose the VOX-K2 if you need a compact 30 cal suppressor for an SBR, short-barrel build, or any host where size and weight at the muzzle are the priority — without giving up full-auto capability.
Choose the Peak 30 if you run multiple calibers and want one suppressor that covers your entire rifle lineup at the best value in the EA centerfire lineup.
Choose the LUX 7.62mm if you shoot precision bolt-action or semi-automatic rifles and want the lightest, most refined 30 cal suppressor for long-range and hunting applications.
All four are US-made, DFAR certified, and backed by Energetic Armament’s lifetime guarantee. All four feature the patented Serial ID Ring — meaning your core can be serviced or replaced without new NFA paperwork. One stamp. For life.
