Q
Carlos, guest, from FL, United States, asked on January 14, 2019

Can I use this compensator on my 9mm carbine with 1/2 x 28" threads?

A
Answered by Sabre, guest, from VA, United States, on March 20, 2019

No, 5.56/.223 is a 22 cal projectile so the bore of this comp is too tight for a 9mm round, it will thread on but when you fire it will destroy this device. You can bore it out if you're handy with a drill press or lathe...

As long as your rifle is threaded in 1/2 x28, it should work great with the Athena 5.56.

Will either model of the compensator work for a bolt action rifle?

Manufacturer Answer
A
Answered by Ultradyne USA, Manufacturer from MO, United States, on October 08, 2025

As long as you choose the correct Athena variant for your caliber and it matches in thread pitch, the Athena linear compensator should work with most bolt action rifles.

JohnFatBottoms, member, from GA, United States, asked on November 29, 2022

Would this linear compensator be a good carry option for my EDC? Thank you.

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on December 02, 2022

The Ultradyne Athena Linear Compensator is not compatible with 9mm. It would work for a 5.7 pistol but I would not recommend it as it was not designed for pistol applications. I would recommend using the Strike Industries Optics Planet Exclusive Strike Micro Threaded Comp, found by using the link below:

Jeffro, member, from FL, United States, asked on August 21, 2022

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on September 02, 2022

The Ultradyne Athena Linear Compensator for 5.56 should work with the CMG 5.7x28mm barrel as long as it is threaded for 1/2x28.

D, guest, from TX, United States, asked on August 13, 2022

Will this work with the sig m400 tread (5.56)? I heard not all compensators fit a sig AR.

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on August 19, 2022

The Sig M400 Tread chambered in 5.56 has a muzzle threaded for 1/2x28. So the Ultradyne Athena Linear Compensator model UD10660 should work fine on the M400 Tread. Sig does not mention anything regarding compatibility issues with certain muzzle devices. If you are concerned I recommend contacting Sig Sauer to confirm compatibility of the Ultradyne Athena Linear Compensator with that particular rifle.

Tony, guest, from VA, United States, asked on May 13, 2022

Will this compensator work on a Hertage rough rider tactical cowboy in 22 lr revolver.

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on August 29, 2022

The .223/5.56 Ultradyne Athena Linear Compensator will work with the Heritage Rough Rider Tactical Cowboy. However, it will be large for that gun. I recommend considering a smaller compensator.

Jay, guest, from FL, United States, asked on September 22, 2021

Can you use this for a 5.7 x 28?

Expert Answer
A
Answered by Tom B, Gear Expert, from IL, United States, on October 19, 2021

Yes, it would be compatible. Per the manufacturer: Rated for the standard cartridges in the following calibers: 223 Rem, 5.56 x 45 NATO, 224 Valkyrie, 224 Weatherby Mag, 22-250 Rem, 222 Rem Mag, 222 Rem, 22 Nozler, 220 Swift, 22 PPC, 22 BR, 22 Hornet, 204 Ruger, 218 Bee

*the 5.7x28 is a .224 diameter bullet, so it would be compatible.
