  • Vents Gases forward
  • Timing nut included for easy installation and indexing
  • 100% CNC-machined quality
  • 100% Made in the USA

Compensation

I’ve found better accuracy. My groups at 100 yards were 1 1/2 to 2”. I can solidly hit 1 1/2 now. At 150 yards sub 2” groups are not hard. A bit more muzzle flash but helps my accuracy. That’s what I wanted. Nice product for the price.

Thanks for sharing your feedback! We're glad you're satisfied with your purchase. Cheers!

Sweet compensator

Super easy installation and does a great job of redirecting sound forward. It does increase muzzle flash a bit, but not to the point of being overbearing.

Very satisfied

High quality peice, noticeable difference in sound reduction, but increased flash as expected.

Thanks for sharing your feedback, Steve. We're glad you're satisfied with your purchase. Cheers!

Second purchase

Bought one of these for my first 10" barreled pistol. Loved it! It really redirects percussion.
Had to have another for my new build!

Thank you for taking the time to leave a review. We are so happy to hear that you loved our Ultradyne USA Athena Linear Compensator on your first 10' barreled pistol. We are glad it was able to effectively redirect percussion. We appreciate your continued support and hope our product serves you well on your new build.

Works great.

Definitely sends the flash and a fair amount of noise forward. Good design.
