The Catastrophic Failure Test
What Happens When You Use .223 in a 22LR Suppressor?
We get this question all the time: “It’s rated for 22LR, but what about other ‘.22 caliber rounds’?” Let us be perfectly clear: the FTW OG is rated for 22LR only. But since we subscribe to the “Mythbusters” school of testing, we wanted to understand exactly how and where the suppressor would fail if someone pushed it past its rated limits.
The Test Parameters: We used a 16-inch barrel AR-based bolt action rifle we call the “Ranch Vulture,” chambered in .223, and fired a standard velocity round. We went into this with a 100% expectation of failure. The primary goal was to study the failure mode.
The Findings: The failure was immediate and catastrophic, occurring on the first shot. However, the core structure held up remarkably well. The threaded portion that attaches to the rifle and the blast chamber reinforcement remained completely intact. The mid-section of the suppressor exploded into pieces, and the last two baffles were launched down range. This test confirms two things: 1) Stick to 22LR, and 2) Even under extreme, unintended stress, the critical mounting and blast-chamber components are engineered to contain the initial pressure spike as much as possible.

“used as intended.”
Sir, “22lr only” is not a suggestion.
