Home Forums Hunting & Shooting Hunting Rifles Replacing my BOSS

I have an M70 with BOSS in .30-06. Muzzle device is ugly, like any break, but it shoots great with both the ported and non-ported modules. I've shot it in the field at deer both ways and I don't recall if one way was louder than the other. Didn't bother the deer either. I'm sure off the bench may be different, but I use ear protection there and it's a non-issue. Not willing to take a chance on accuracy cutting it off, not to mention loss of barrel length and cost. I just ignore it.

Rem 700's were never made with the BOSS tuner/brake

It was a US Repeating Arms/Browning thingie for Winchester & Browning rifles

Called the CR. Conventional Recoil.

No holes to act as a brake, just use for tuning.

The chart may be hard to read but just let me know your caliber and I'll give you the part #. The settings are the same for the brake and CR.

Your 300 WM Stainless Stalker is R720DS

Thanks for all the input guys. I think I'd be good with the CR model. Not the prettiest thing but might achieve what I want. I'm going to go out and shoot it without the BOSS also just to see what it does. If it shoots good I can have a thread protector fabricated for it as another option.

My BOSS equipped M70 was a 30-06. I got the CR and dialed in good accuracy with the now discontinued Federal High Energy Nosler Partition load. I took it on an elk hunt with visions of cross canyon kills. I almost felt guilty when my shot came at 40 yards in the timber. But the guilt passed quickly. :-)

Don't like crap on the end of my barrel. Brakes are noisy more so than normal. So you can buy an unported version. More money down the drain. Cut it off recrown swirl more money down the drain. Now the barrel is to loud because it is to short. Rebarrel swirl more money down the drain. Now you have more money in the pos than you will ever get out of it. Congrats now you have become a member of the custom gunowners club, a subsidiary organization of the if it's got tits or turns its gonna cost you money club. Sell it and buy a gun that shoots without spending extra money on. Mb

It always works that way.

Where is the fun in that ?

This website would not exist if everyone thought that way. Members buy uber actions, stocks and barrels spend multiple thousands and then they are in the classifieds within weeks selling for much much less than they have in it . They have to churn the Economy.

Dude! Someone has to do it!

Guilty of this as well.

The key word here is "they" let someone else churn and piss away their cash.mb

Got to have the greatest latest .

I believe I’ve done this as well. Just once or twice…. 😵‍💫 These days I try to pick up rifles that have already had the significant ‘smithing investment already done. In the case of my A Bolt it’s a shooter from the factory. The only issue is that it’s too damned pretty to hunt hard in these mountains. All I do is worry over it in the woods.

If you call browning they will send you the boss CR for free. At least they used to, got one back in December last year after a call to them.

Words of wisdom!

I have a Winchester 70 with the BOSS muzzle brake. It has worked for me, though you can go thru a bunch of ammo if you're not careful. Ihe brake is loud but I hunt from stands only so I wear an electronic hearing muffs. Recently I experimented with reduced velocity loads that have proved to be very accurate. So, I replaced the BOSS brake with the CR BOSS (Conventional recoil BOSS) without the ports and, as fate would have it, I use the same setting as with the BOSS brake. Good system.

I've pulled several of them and cut 1/4" off the threads and recrowned and put suppressor mounts on them. The ones I cut were all threaded 9/16x24 which is not an uncommon size for suppressor mounts/muzzle devices. Regardless they all shot well after cutting them down. Even if you pay a gunsmith to do it, it's still $600-$700 less than getting a barrel installed.

Get the CR for the short term
I put a can right on the 9/16-24 threads, with a 5/8” to 9/16 shoulder less adapter

You can screw it in and out like a BOSS to tune
3/4” or less groups from a 30y factory rifle will be the result

I am surprised there hasn’t been a resurgence of the old brownings because of this
