ECCO Machine Five By Five 5.56mm

Developed specifically for short barreled 5.56mm rifles, Five By Five gets it’s name from it’s 5″ long, five baffle design. Featuring our unique progressive baffle profile, Five By Five is able to offer truly astounding suppression from such a small can, coming in right at 140 dB at shooter’s ear on a B&K Pulse system when fired from a gas adjusted 10.5″ AR-15 using ball ammunition. It was carefully developed to balance back pressure with muzzle end suppression on these short barreled semi automatic host weapons, and we are truly proud of the end result.
