I got 99 problems, and the BOSS is one

[RANGER3BN]

The "problem"

Winchester Model 70 super Grade 7mm Rem Mag with BOSS system
Graduation present and want to keep in original configuration
Great shooter with BOSS, well under 1 MOA with typical results of .6 to .75 (not a problem)
24" barrel, 26" with BOSS installed, 9/16-24 thread pitch
F...........ing...........LOOOOOUD
Do not want to cut down to establish proper shoulder for an old 9/16-24 direct thread 30 cal. can I have


Solution:

Some Jedi in this forum knows a manufacturer or custom shop that will sell or produce an abortion of an adapter that will thread female 9/16-24 to male 9/16-24 with proper shoulder

You cannot have an adapter with the same thread pitch inside and out.

Does your can have a HUB mount. If so, get one that is 5/8-24 and get a 9/16-24 to 5/8-24 adapter.

Or just forget the internet BS about “proper shoulder” and thread your can on, snug it up, and shoot it.

Not goona lie. The thought of a m70 supergrade with a can hanging off of it. Gives me the same heebee jeebee's as all those tacticool lever guns...dont do it bro

I assume you are thinking of something like this but made for rifles? I’m sure any decent machinist could make a female to male adapter like this with suitable materials.

Yeah, OP, that sounds like a cool gun, but that might be a bit of a tough one, if not an outright money pit to do right. Especially if the BOSS has a lot to do with that individual gun's accuracy. Have you ever grouped it with the BOSS off?

 

[Steve300xcw]

I'd honestly bob that thing just behind the threads and enjoy your sweet ass rifle that is now way quieter.


Btw a supergrade for graduation? My folks didnt love me that much

You need to look for the BOSS CR. CR is for conventional recoil. It's basically a brake without holes that still fits the thread and tunes.

There's quite a few BOSS-CRs on ebay

My father has a Winchester 70 all weather with a boss. It is threaded 9/16-24 as well and has a super long tenon. Also there is a plastic “key” in the tenon. This must give some resistance to the BOSS threading.

Well I bought a HUB mount for 9/16-24 threaded it on, threaded on a suppressor and quit worrying about it. The rifle shoots awesome even with a heavy suppressor on a light barrel.

Long time Boss owner from when Browning 1st introduced them on the Abolt back in the 90's. My Abolt @ medallion 7 mag came with both the ported brake, which I immediate took off (as you said very loud) and installed the CR brake. If you would like, I can take a pic of my Browning box it came in. It has the different model numbers for the different calibers. The CR tuner is basically like the EC tuner. And it works. I still to thid day get .5 moa out of hand loads for mine and its a 30 years old gun. The barrel thread have a slot in it. There is a plastic strip that goes in there to make turning the tuner hard. It gives it a lot of resistance. I lost mine, contacted browning and was told to use weed eater string. Did that and works great.






If you have a blued M70, the 7mag version is R720BP, for Matte M70, R720BM and if you have a SS M70, get R720BS. and yes, its 9/16-24 threads
