Replacing tuner with muzzle brake

[Rumrunner]

I really hope this body of knowledge can help. I recently acquired a Winchester model 70 in .416 Rem Mag that has a tuner. I would like to replace the tuner with a muzzle brake. I have been told that the tuner has different threads than a muzzle brake and can’t swap them. So ok. Does anyone know of a place that will custom make a muzzle brake with different threads? Or a company that makes muzzle brakes that will do a custom thread?
Thanks.

I'd find out what the threads are before looking for a custom job

I wonder if this is the BOSS system? It was my understanding that Winchester made these with either a break or just the weight to fine tune the barrels. You might look for the BOSS break. Not sure if Winchester parts might still be available. You could also probably just have the Tuner drilled out, same as a break. You might try these guys out as well.

Wow. Not sure how I managed to screw up a simple post so royally. Thank you moderator.

The threads are 5/8-28. There is about 1.3 inches of threaded barrel. I would like to get a muzzle brake threaded to 5/8-28. Not sure if an adapter might work?

That is a lot of threaded barrel. I still think having the tuner drilled out (turned into a muzzle brake) might be the easiest solution. Otherwise I believe you may need to have a smith cut of part of the threaded barrel. 1.3 inches is a lot of threads. Just throwing out ideas.

gentrycustom.com DO 5/8-28 IN A COUPLE STANDARD THREAD LENGTHS, THEY ARE ALWAYS REAL HELPFUL SO MIGHT DO A CUSTOM ALSO. I REALLY LIKE THEIR BREAKS.

@Rumrunner
Any decent gunsmith can ream out the old threads of a muzzle brake and either cut new threads or make an insert that could be srcewed into the brake then onto the barrel.

Ok. So I have spent the last few weeks researching what I have and evaluating everything, I think. First lesson I’ve learned on this journey is to question what you’re told. I was told by someone I thought was very knowledgeable that I had a tuner on the rifle. It does have a tuner but it also has a radial muzzle brake. I think that was the source of some of the confusion regarding the length of the threaded portion. My apologies for not doing adequate research before I asked questions, second lesson learned.
I plan to continue conversations with some of the suggested places to make a custom brake or discuss drilling and rethreading a 7/16-24 to 5/8-28. Not 100% sure if that will work until I ask some more questions. Everything I have read has said the radial muzzle brake is not very effective. If I decide to get a better brake I can resign myself to shooting away from others at the range. I’m ok with that. The toss up is if I should leave it on in Africa or remove and install a thread protector. I recognize the PHs really don’t like them and you really don’t feel recoil when shooting game but if I have very high confidence on shot placement with the brake that is a significant factor.
There is also the opportunity to begin reloading and work up a load that reduces recoil.
Or, I continue with the current setup, learn to handle the recoil better and gain the confidence in shot placement. At least I have a year or so to get things figured out then a year to practice.

@Rumrunner
The radial port muzzle brake reduces felt recoil by upto 30% but the tanker ( angled brake) reduces recoil by upto 50%
I find the radial port adequate but if using it probe the kick up a lot of dust.

I think the M70 is on the lighter side for a 416, at least for me. I have the Ruger RSM 416 Rigby and the recoil is stout. I have a brake on mine but plan to load down a bit. I might go to the 350 gr Barnes and load it at the starting levels, then remove the brake. I have the 375 in the Ruger RSM as well and it is very pleasant to shoot.
