Pin weld possible?

Manufacturer Answer
A
Answered by Breek Arms, Manufacturer from MN, United States, on March 05, 2025

These do not come with a pin hole pre-drilled, you would have to drill a hole yourself in order to pin and weld to a barrel.

Does this work for 5.56

Manufacturer Answer
A
Answered by Breek Arms, Manufacturer from MN, United States, on January 15, 2025

If you choose a muzzle device that has a .223 or 5.56 caliber it will work for your 5.56, be sure to check that the thread pitch matches the standard 1/2x28tpi as well.

What is the outer thread for?

Manufacturer Answer
A
Answered by Breek Arms, Manufacturer from MN, United States, on January 15, 2025

This listing on Optics Planet has 2 different styles on it currently, so be aware that not all options currently on this listing have the outside threading. But all of our outside threaded options are for our Castle Blast Shield which is a 13/16-16tpi thread pitch.

Joseph Tourtillott, member, from MI, United States, asked on December 04, 2023

On the .30 cal one, will this not work on a .300 blackout and why?

Manufacturer Answer
A
Answered by Breek Arms, Manufacturer from MN, United States, on March 19, 2025

Yes, a .300 blackout is a .30 caliber bullet. So as long as your barrel has a matching thread pitch of 5/8 x 24 tpi then the .30 caliber option will work perfectly!
