two points:
A GOOD muzzle brake will reduce from 70 to up to 85%.
I hate companies that make their stuff proprietary just because.
Muzzle brakes and silencers have fairly common threads(some variation based on barrel profile and caliber)
Making your own threads is total BS...and the reason I own no Browning.
PS, years ago the standards for PC upgrades was likewise fairly standard.
HP and Apple made everything from memory standards to Power supply unique.
Reason I still find in hard to understand why sheeple flock to APPLE.
Their kit is made to fail, and impossible to repair (sealed, locked, soldiered memory batteries etc. etc. etc.)
Long rant....TLDR
Buy a Tikka instead of browning.
