Devour felt recoil. Browning has found the secret to improving shooting comfort and improving accuracy with the Recoil Hawg muzzle brake. If you've spent time behind a rifle, you know that the repeated jolt of felt recoil experienced by long range shooters and magnum calibers takes a toll, both physically and mentally, and can affect accuracy. Browning developed the Recoil Hawg to counter these effects, reducing recoil up to 76% (depending on the caliber). Specially designed directional porting also reduces muzzle jump significantly to keep the target in your scope. Because the porting blows gases up and to the sides, your dust signature is also minimized. With the Recoil Hawg, you'll experience reduced discomfort and fatigue during longer range sessions. Accuracy is also less likely to suffer because of reduced fatigue and flinching. The Recoil Hawg will fit most bull and heavy-sporter profile rifle barrels with a minimum barrel shoulder of .700" and 5/8"-24 TPI or 1/2"-28 TPI muzzle threads. The Recoil Hawg will not fit X-Bolt Speed rifles and other rifles with sporter-weight barrels (M13 x 1.25 or M13 x .75 threaded muzzle).
