Energetic Armament EA33 VOX End Cap 5.56mm Stainless Steel Nitride

The Energetic Armament EA33 End Cap is a drop-in suppressor accessory designed for the VOX-series suppressor family, allowing end users to dial in performance for 5.56mm hosts. The cap features a tighter bore aperture specifically sized for 5.56/.223 rounds, giving the can a caliber-appropriate exit geometry in place of the larger 7.62mm default. It is machined from American-made 17-4PH stainless steel and finished in a black nitride coating for corrosion resistance and a low-gloss appearance.

Whether you're tuning a VOX-series suppressor for rifle use, the EA33 installs in place of the stock end cap with no modification required. The matte nitride finish blends with most suppressor and muzzle-device color schemes, and the stainless construction keeps weight to roughly an ounce. Built and finished entirely in the USA, this is a brand-new factory component for shooters looking to optimize a VOX suppressor for 5.56mm duty.
