Thunder Beast: Spiro-DT, .223 Cal Suppressor TBAC

$995.00

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).

It is a "Go To War" suppressor designed for 10.5", 5.56mm caliber assault rifles. It works great on .223 / 5.56mm caliber gas guns from 8" up to 16" or longer. The SPIRO is designed to be put on your 5.56mm carbine and shot a lot, only being removed for firearm maintenance and suppressor cleaning.

The SPIRO is made from Haynes 282, a nickel-chromium-cobalt-molybdenum "Super Alloy." It is stronger than Inconel 718 and exceeds Inconel's operating temperatures by about 500 degrees F. This makes the SPIRO almost indestructible. While our other "full auto rated" suppressors are guaranteed to last 10 cycles of the 8-mag SOCOM SURG test on a 10.5" barrel, the SPIRO is rated for over 20 of the same cycles using an 8" barrel instead of a 10.5".

People have been talking about "low back pressure" for a while, but there hasn't been an objective method to actually quantify it. Thunder Beast Arms Corporation wasn't satisfied with that, so they invented the TBAC Method of Measuring Back Pressure, and then we used the same sound-test setup we use at the SILENCER SUMMIT to make a very low-back-pressure suppressor that is also unbelievably quiet at both the muzzle and at the shooter's ear, for a suppressor under 6".
