I have a growing bar 300 win mag and want to put a muzzle break but the bore is not threaded do you have tools to thread that rifle so I can install

Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on December 05, 2022

Unfortunately, we do not carry any barrel cutting kits that would allow you to thread your barrel. You can either purchase a new barrel that comes threaded or have your barrel threaded by a professional.

Hello, I have a Bargara Premier .308. The diametr neer muzzle is 23,5mm. Which model I must to choise? Ultradyne Apollo 5/8X24 LR or model .308 MAX

Manufacturer Answer

Answered by Ultradyne USA, Manufacturer from MO, United States, on July 22, 2026

Hi, thank you for reaching out! Both brakes are great and they will work with your rifle perfectly fine. If you are wanting a brake that is lighter and more compact, we would recommend going with the Max. You want to make sure that you have a minimum barrel length of 16" which your rifle does have a barrel length of 20" so you should be good.

so this will fit my ruger precision .300 Winchester magnum rifle ?

Manufacturer Answer

Answered by Ultradyne USA, Manufacturer from MO, United States, on March 12, 2026

Yes! From the specs I can find on that rifle it should be threaded 5/8 X 24 and .875" at the muzzle so this brake should fit perfectly.

William Hogan, member, from TN, United States, asked on January 02, 2026

I have a Savage 110 7mm mag, what timing nut is included with this item? Ultradyne give 2 options. The .875 and the 1”. I am looking for the .875

Manufacturer Answer

Answered by Ultradyne USA, Manufacturer from MO, United States, on January 19, 2026

Hello William. You would need to measure the shoulder of your barrel to confirm if it's larger than 7/8" (0.875") ultimately, but most standard barrels should work with the 0.875" nut. This option here is the package that includes the 0.875" nut to confirm.

Trucker, member, from MI, United States, asked on August 16, 2025

Will UD11200 model # work with .338 ARC with 5/8x24 threads?? And do you know what size Timing nut is included?? Thanks

Manufacturer Answer

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

The Apollo LR .338 (UD11200) should work great with most rifles chambered in .338 ARC with 5/8 x 24 threads. Unless your setup has a heavy barrel, it likely would need the standard 0.875" (7/8") nut.
