Product Description
Low Back Pressure Gas Gun Suppressor
Extreme Duty/Full-Auto, 5.56mm
The SPIRO is a low back-pressure gas-gun suppressor that has excellent sound suppression levels at both the muzzle and at the shooter’s ear.
You no longer must compromise and have your gas gun suppressor be “Low back pressure but loud at the muzzle”
The SPIRO increases back-pressure gas flow by only approximately 50% compared to a bare muzzle (most LBP are 35-85%), which is 3X less gas than a Dominus-SR. The SPIRO only increases the cyclic rate of an Mk18 by about 5% (compared to 43% for a Dominus-SR; most LBP 3%-10%). This is while keeping Shooter’s Ear peak dBA at 136.8 (LEq dBA 124.2), and milspec-left muzzle position 135.4 dBA (LEq dBA 122.5). For reference, the Dominus is a few dB louder at the milspec position and at the shooter’s ear.
