Ultradyne Apollo S Compensator 6.5mm 5/8x24 Thread - Precision Muzzle Brake

The Ultradyne Apollo S Compensator in 6.5mm is a precision muzzle brake engineered for shooters who demand faster follow-ups and tighter shot strings. Built on applied research into rifle dynamics, this compensator manages the three forces that disrupt accuracy during firing: felt recoil, muzzle rise, and gas direction. If you're running 6.5 Creedmoor, 6.5 PRC, or any other .264-inch caliber, the Apollo S threads onto 5/8x24 TPI muzzles and delivers the recoil reduction and muzzle control that competitive shooters and hunters rely on for cleaner transitions and quicker hits.

What sets the Apollo S apart is its chambered internal design. Rather than simply venting gas outward, it channels and directs gases in a way that minimizes both the blast signature and the felt push-back to your shoulder—while keeping those gases away from your face and peripheral vision. This matters whether you're on the competition line or in the field. Machined from 416 stainless steel and built in the USA, it weighs just 4.4 ounces, so it won't slow down your barrel or bloat your profile.

The compensator ships with a shrouded timing nut, so you're ready to thread it on and zero in. If you're already invested in Ultradyne's quick-detach Dynamounts ecosystem, the Apollo S integrates seamlessly. This is a no-nonsense brake for shooters who value precision engineering and repeatability over flash or hype.

Frequently Asked Questions

What calibers does the Apollo S Compensator fit?

The Apollo S is designed for .264-inch (6.5mm) caliber barrels and smaller. It works with 6.5 Creedmoor, 6.5 PRC, .260 Remington, and other 6.5mm cartridges, as long as your barrel is threaded 5/8x24.

What thread pitch do I need?

The Apollo S has a 5/8x24 TPI thread pitch. Verify your barrel's thread spec before purchasing—this compensator will not fit barrels with different thread pitches like 5/8x32, .624x28, or metric specs.

Is the timing nut included?

Yes. The Apollo S ships with a shrouded timing nut, so you have everything needed to install it once it arrives.

Can I use this with Ultradyne Dynamounts?

Yes. The Apollo S is compatible with Ultradyne's quick-detach Dynamount system if you want the option to remove and reattach the brake without tools.
