Will this work on a ruger 6.5 PRC?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on May 16, 2023

Yes, the Ultradyne Apollo S Compensator model MPN:UD10250 will also work with rifles chambered in 6.5 PRC that use 5/8x24 threads as both 6.5 Creedmoor and 6.5 PRC have the same bullet diameter.

The Ultradyne Apollo S Compensator 6.5 Creedmoor model has threads for 5/8x24. So it will work with a Ruger American Predator in 6.5 Creedmoor.

Massey, member, from AZ, United States, asked on September 06, 2022

What Apollo would be best for a 300 ham'r on a 18" barrel with 1-13 twist?

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

The Ultradyne Apollo S Compensators will not work with a rifle chambered in 300 Ham'r. You will need the .308 model of the Ultradyne Apollo Max Compensator at the link below. This is model number UD10710. It will work with your barrel if it is threaded for 5/8x24 and has a minimum thread length of .600".
