About This Suppressor
The Thunder Beast Arms Spiro is a Haynes 282 rifle suppressor for 5.56 carbines. It has an MSRP of $995. Thunder Beast puts it in its own Hard-Use/Full-Auto Mod 1 durability category, with a maximum rating of .223/5.56 and .22 Creedmoor.
It is sold either as a direct-thread can in 1/2-28, with a Nord-Lock washer included, or as a HUB 1.375x24 version with no mount in the box. In direct thread form it adds 5.3 inches to the rifle. The body is 5.9 inches long and 1.8 inches in outside diameter.
If you're cross-shopping, the Rugged Razor556 has an MSRP of $836, is 1.5 inches across and mounts on a taper-lock brake. The Dead Air Sierra 5 has an MSRP of $859 and shares the HUB thread option, at 13.3 ounces with its Xeno adapter. Of the three, the Spiro is the one sold without a mount in its HUB form.
Strengths & Limitations
Pros
- Haynes 282 through the body.
- Two mounting routes from one model, direct thread or HUB.
- A Nord-Lock washer comes with the direct-thread version, so the can stays put on the barrel.
Cons
- The HUB version has no mount in the box, so budget for one.
- Heavier than the 5.56 cans on this list that cost less.
- Rated to .22 Creedmoor at the top, so .30-calibre hosts are out.
