My understanding is that Browning does not retrofit bosses to rifles and I've not heard of any similar system on the market. As far as I can tell you would have to get a regular non adjustable brake installed.
Browning won't do it. Even through the custom shop. I tried in vain to get a BAR in .243 with a BOSS on it for a customer of mine who had just had some painful back surgury but refused to give up another season in the woods (my kinda guy). This dude owns a hospital, money was nothing but a thing for him, but it didn't matter, they wouldn't even do it through the custom shop.
I don't know any gunsmiths who will install those things either. Our gunsmith outsources all of that stuff to magna-port or accubrake.
The BOSS system really does work though. I had one when I was younger and the muzzle brake allowed me to shoot a 30/06 even as a 9 year old kid who weighed 70lbs wet. But, the brake as opposed to the conventional recoil (CR) model can do significant damage to your hearing if you do not wear earplugs, even when hunting.
I think the non-braked barrel tuner would certainly be a worth-while investment but don't be discouraged from the boss if recoil reduction is also what you are looking for. Just be aware that it comes with a price... increased muzzle blast.
One of the most important pieces of equipment that you will take hunting is a good quality pair of optics and they take some care to give you the performance that you want. So here are a few tips.
Use some alcohol and cheese cloth to clean the lenses. I will usually pick up an extra cleaning kit from my optician when I have my eyes examined.
Don't touch the lens with your fingers. If there is a stick or a bug on them blow it off.
Use the lens covers. They are there...
