VOX-K2 Compact 7.62mm Suppressor — 10.4oz, Full-Auto Rated

VOX: Latin for voice. The voice of your gun — raise your standards and lower your voice.

The VOX K2 represents the next evolution of the VOX line of Energetic Armament silencers. Purpose-built for shooters that require a hard use, high temperature silencer that is light and compact. At 10.4oz and 4.9 inches, the K2 improves weight efficiency (dB/oz) by 60% at the muzzle and 25% at the ear over the legacy VOX K in testing performed on a Mk18 rifle. Where a compact, high performance silencer is needed, the VOX K2 delivers 54% greater length efficiency (dB/in.) at the muzzle and 20% greater efficiency at the shooter’s ear.

C300 Maraging Superalloy Core — Universal HUB Mount Compatibility

The VOX K2 features a laser welded and nitrided C300 nickel-cobalt superalloy core with industry standard 1.375×24 HUB pattern mount — giving shooters access to a wide array of mounting options in addition to the removable direct thread adapter that ships with the silencer. The industry-first wipe cap is standard equipment, allowing use with or without the wipe depending on your needs. The VOX K2 also accepts accessory flash hider end caps in both 7.62mm and 5.56mm. Ships standard with a combination cap/mount spanner and VOX Blox vise block.

Patented Serial ID Ring

The VOX K2 features the Energetic Armament patented Serial ID Ring, standard on all EA centerfire silencers. This patented ring ensures best-in-industry support should anything happen to your silencer such as a baffle strike. Backed by a lifetime guarantee with fast warranty re-core turnaround.

C300 Maraging steel vs titanium vs stainless strength comparison — Energetic Armament VOX

The data shown in the above graph is taken from Metallic Materials Properties Development and Standardization (MMPDS) — the US Federal standard for metallic materials properties used by the DoD (formerly Mil-Handbook-5), FAA, and NASA for flight critical design and procurement. This represents statistically validated materials properties for Aerospace Materials Standards (AMS). Data shown for C300 Maraging Steel is per AMS 6514 (bar) and for 17-4PH Stainless is per AMS 5643 (bar).

Thinner Walls, More Volume — Better Sound Attenuation at 10.4oz

The ultra strength of this unique aerospace alloy allows the VOX-K2 to achieve very low weight at only 10.4oz without sacrificing durability. The high strength alloy allows thinner walls which not only optimize low weight but also increase internal volume while maintaining a small outer envelope. More internal volume means better sound attenuation.

Compatible with All Industry Standard QD Mounting Systems

The VOX™ is compatible with all industry standard quick-disconnect mounting systems including the Project E. This allows the operator to use the muzzle devices they already have and makes swapping your VOX™ between guns simple and convenient.

Wipe End Cap — Ultra-Quiet Subsonic Performance Standard

The end cap of the VOX-K2™ is removable and features a wipe holder as standard equipment. A high temperature rated silicone wipe provides ultra-quiet sound performance when using subsonic rounds. The wipe forms a seal to the exiting bullet to control gas flow and bring the ultimate quiet to your shot. The wipe is easily removed for heavy supersonic, high power shooting when needed. The VOX-K2 is quiet… really quiet… with a low, even tone that gives your rifle the voice you want.

Lifetime Guarantee & Fast Return Warranty Re-Cores

Energetic Armament stands by our silencers with a lifetime, no-bullshit guarantee. If you need us, we will be there to take care of your silencer. Our patented Serial ID Ring construction allows us to repair damaged silencers quickly and get you back on the firing line.

Wipe End Cap — How to Replace Silencer Wipes

The wipe material is 1/8″ reinforced silicone sheet (McMaster-Carr PN 3635K17) that is punched with punch (McMaster-Carr PN 3427A26) out 1-1/8″ dia disks. The use of an end grain wood block or soft plastic anvil is recommended. The nose hex is 1-1/4″ (wrench supplied) and the wipe retainer uses a 9/16″ socket. All threads should have an anti-seize applied when reassembling (McMaster-Carr PN 1288K12).

Wipes may be replaced by a dealer or users can repair their silencers; they just can’t manufacture and stockpile silencer parts. Making and replacing wipes 1:1 is acceptable. You cannot make them for other people or have more than one at a time. The old wipe should be destroyed before a new one is made.

Per BATF regulations Energetic Armament does not sell replacement wipes. This guide DOES NOT constitute legal advice and firearms laws change regularly. Please consult your dealer or an attorney for guidance with all laws and regulations.
