ODIN Works Suppressors: Enduro & Tiduro

ODIN Works has a new suppressor – the Tiduro – which I put to the test against their Enduro multi-caliber suppressor. In addition to the recoil rig, I have sound level testing for the first time ever! Be sure to watch the full video and read on for the results.

About the ODIN Works Suppressors

Both the Enduro and new Tiduro are modular 9mm/multi-caliber suppressors rated for semi-auto. They both measure 9.7” in length and 1.5” in diameter, featuring five removable, aluminum baffle extensions. Removing one or more of the extensions shortens the length of the suppressor. QD and direct thread mounts are available.

The biggest difference between the two is that the new Tiduro has a 3D-printed titanium main body construction with two integrated baffles. The Enduro has a 17-4 stainless steel main section with two removable steel baffles.

This difference in materials also means a difference in weight. In full configuration, the Tiduro weighs 3.8 ounces less than the Enduro. The Tiduro has an MSRP of $1099, a bit more than the $799 MSRP of the Enduro.

The optional addition of the ODIN Works PSI muzzle device makes these suppressors the most configurable we have tested to date.

The 9mm PSI comp muzzle brake has a 2-port design of 7075 aluminum with a Type III anodized hard coat. It weighs 2.5 ounces and is 1.925 inches in length.

Shooting

I’ve shot both the Enduro and Tiduro using supersonic and subsonic ammunition. Using a shortened configuration with the .338 ARC, I was especially happy with how Hornady’s .338 ARC 307 Grain Sub-X subsonic ammunition and Hornady Black .338 ARC 175 Grain Hollow Point Match Ammunition performed.

Keeping .308 “Shorty” in a compact configuration with only one aluminum baffle, I shot handloads using Berry’s .300 Blackout 220 Grain Spire Point plated bullets.

These are economical but still get the job done. I repeatedly hit a game-sized D-M steel target at 200 yards off a tree branch with this ammunition.

Sound and Recoil Rig Testing

The Ultimate Reloader Recoil Rig is based off of a design from Cal Zant from the Precision Rifle Blog and measures forces at the buttstock at up to 200,000 samples per second.

It utilizes the DEWEsoft Sirius 8-Channel DAC and a PCB Piezoelectronics load cell to capture directly comparable results.

I also have PCB Piezoelectronics scientific microphones to capture sound data.

To capture sound data, I placed these microphones 0.4m away from the muzzle, per NATO guidelines.

The first tests I ran were with .308 Winchester. I used supersonic loads for both the sound and recoil testing.

The quietest configuration was the Tiduro minimum baffles with PSI brake. This was only 0.5 dB quieter than the Tiduro with all baffles.

t is important to remember there is considerable clearance between the baffles and the .30 caliber bullet. I placed Shorty in a Foundation Stock for the recoil rig test.

There was the most significant difference between the bare muzzle and the Tiduro with all baffles, but the rest of the configurations were comparable.

Just as in sound testing, the results for the Tiduro with all baffles and the Tiduro with minimum baffles and PSI brake were very close.

I conferred with ODIN Works’ engineers about this. They had utilized a .300 Win Mag in their testing, so I decided to run more tests, utilizing a variety of brakes. The DEWEsoftX software revealed the recoil reductions I’d expected to see.

.300 Win Mag has a lot more gas pressure than .308 Win., which is why there wasn’t much of a difference if any in the .308 tests.

Also notable is the difference in buttpads between the .308 and .300 Win Mag. The .308 had a very rigid buttpad that barely moved in contrast with the cushy buttpad of the Bergara .300 Win Mag.

Both provide accurate data, but the forces are stretched out longer over time with the cushy buttpad, lowering the peak forces. This is the point of a good buttpad!

Mystery solved! When it comes to a suppressor brake, the more magnum the cartridge, the more difference you will see.

Conclusion

I really like the configurability of both the Enduro and Tiduro suppressors and the ability to add a brake to further reduce recoil on magnum calibers.

9mm provides maximum caliber flexibility, though it isn’t optimized for sound reduction. I also found that shorter suppressor configurations worked best for subsonic loads.

Overall, choosing between Enduro and Tiduro will come down to price as well as the weight tradeoff considering the balance point of the rifle you intend to put it on.
