VOX: Latin for voice. The voice of your gun- Raise your standards and lower your voice…

Energetic Armament is disrupting the status quo again. The VOX silencer represents the next level of precision engineered rifle silencers. The silencer core is CNC welded from C300 Maraging (MARtensitic AGING) nickel-cobalt superalloy. Energetic Armament is the first silencer manufacturer to apply this ultra-strong alloy to a silencer. This aerospace alloy was developed and used by NASA to meet the extreme high-temp stress requirements of rocket motor casings with an incredible strength to weight ratio. Tensile yield strength is a measure of how much force a material can withstand before it begins to fail. Other manufacturers are stuck with 17-4 H1150 Stainless which has a yield of 100ksi or 6Al-4V titanium which has a yield of 120ksi. The C300 maraging steel used in the VOX is heat treated to achieve a yield of over 270ksi. What’s more: It has more strength at 1,000°F than either stainless (17-4 H1150) or titanium have at room temp! The unique material science of the VOX means you don’t have to compromise- you get the rugged full-auto rated capability of a heavy silencer with the light weight of a less rugged titanium can. No other silencer offers this spectrum of capabilities and features.

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.
