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
A
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.

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
A
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.
