Description

ASE ECO Rimfire Suppressor .22cal 1/2x20 Thread

The Ase Utra ECO ring fire suppressor has excellent soundproofing and is designed for pistol and rifle use. ECO Suppressor is made of anodized aluminum. The suppressor allows the use of iron sights or low-mount optical sights. Standard threads for the suppressor are also 1/2 "x 20 UNF. Due to the simple design, the ECO suppressor can be easily disassembled for cleaning and maintenance.

Specifications:

➼ Caliber: .22LR
➼ Weight: 105 g
➼ Diameter: 28 mm
➼ The overall length of the suppressor: 140 mm
➼ Added length to weapon: 125 mm
➼ Net sound suppression : 
    (1m left of the muzzle, rifle) : 30-35 dB(A)
    (1m left of the muzzle, pistol) : 27-30 dB(A) 


PERFORMANCE:
The suppressor reduces the sound pressure level by about 3035 dB on a rifle and c. 2730 dB on a pistol. It should also be noted that the first shot with the Ase Utra suppressor is just as quiet as the next, so there is no significant "first-round pop".

The reduced sound pressure level eliminates the risk of hearing damage for shooters and also significantly reduces ambient noise. ASE Utra edge fire extinguishers comply with the latest personal exposure limit set by the European Directive 2003/10/EC (140 Pa or 137 dB(C)).
