Hawkins Precision’s Backdraft is the newest self-timing muzzle brake in the line-up. This 4-port brake features rearward port geometry to increase recoil reduction for heavy hitting cartridges. Think of it like a Tank ST turned to 11.
 
The Backdraft also shares the same 3/8 Hex/Allen opening up front so users can torque down their muzzle brake to the same torque value every time. 
 
Specifications: .30 Cal, 0.750” Outside Diameter, 1/2x28 threads. Does not come with locking collars due to a lack of material.
