Description:

The Vortex is machined from 8620 bar stock steel, then case-hardened to provide a tough core and hard surface for maximum strength, black-parkerized finish. 21⁄4″ long, .861″ diameter. It is Sound Suppressor capable. It is not a timed item, when it is tightened that’s where it is. The Vortex does not required the use of a lock washer.The Vortex conceals the flash essentially 99.999% - even on full auto.

The Vortex carries a conditional lifetime guarantee. It is in service with many Law Enforcement agencies throughout the U.S. The Vortex has been used in combat by the U.S. Military.

Four specially angled flutes dissipate the gas but contain the unburned powder allowing increased residual burn for less visible flash. It incorporates a helix design essentially tightening itself when the weapon is fired and helps align exiting barrel gas to improve accuracy with all bullet types.

The world’s best flash suppressor now
available for use with SEI Direct Connect (DC)
Sound Suppressor
Based on the combat-proven Vortex® 5.56mm G6A1
system, the definitive development of the patented
Vortex® design now features a 40% increase in structural
rigidity. The new G6A2 model features our patented
15-degree helix, guaranteeing a complete propellant
burn and negligible flash, unlike the standard issue
closed-end “bird cage” unit or competing straight-flute
designs. Right hand helical flutes will not loosen under
sustained fire. The flute configuration is 40% stronger
due to greater mass. The aligning of exiting gases helps
to improve overall accuracy.
The G6A2 also serves as a quick-connecting interface
for our new M4DC CQB Sound and Flash Suppressor.
SEI suppressors are only available to USG/LE and FMS
customers via direct factory sales. The highest degree
of flash suppression is gained using M-193, SS-109
(M855), and MK 262 service ammunition.
Also, our new Blank Fire Adaptor (BFA) is a quantum
improvement over the current issue item. With a
powder-coated billet steel body and a stainless steel
center shaft, the BFA has a service life well beyond that
of the standard GI issue type. A grenade pin is attached
through the center shaft to help prevent loss in the
field. Also, the SEI 5.56mm BFA is designed to be used
on all Vortex® M-4, M-16-series and the M-249 series
weapons, thus allowing consumers to maintain only one
standard type BFA at the unit level.
