SKU: 419HF-BN-6MM
Built for hunters and precision rifle shooters who want a brake that installs cleanly and stays aligned, this modular system is designed around simple setup and repeatable use. The self-timing design uses a universal adapter and hand-tightened collar, so timing the ports does not require tools, and the brake can be removed and reinstalled without changing zero. Rearward-facing ports and proprietary port geometry are intended to manage recoil and muzzle rise, while caliber-specific options and thread choices help match the brake to a range of rifle setups. It is offered with Black Nitride or raw stainless brake finishes, with black universal adapters, for shooters who want a practical, purpose-built muzzle device rather than a one-size-fits-all accessory.

The product is offered in four caliber selections: 223/6mm, 6.5mm, 7mm/308, and 338. The description lists example cartridges for each selection, and notes that the 338 option is for bullet calibers up to and including 0.338.
No tools are needed to time the brake itself. The description says it uses a simple round knurled nut for tool-free timing, and the brake is designed so it will not turn as you torque the collar to lock it in place.
The universal adapter is available in 5/8-24 and 1/2-28. The description also states both are class 3 fit.
The product description says return to zero is excellent, and that removing and reinstalling the brake should not require a zero change. That said, actual results can depend on the rifle setup and installation.
The brake is listed in Black Nitride finish or raw stainless, while the universal adapters are listed as black nitrided.
