Never owned a rifle with a brake until I got the Mark 5 Live Wild in 7mm Backcountry with the Accubrake muzzle brake. It makes it so easy to shoot, that my wife can shoot it and she’s only 5’2″ 128 lbs. She has a .308 that is all over the place if she shoots with one hand from a rest. Well now she’s getting a Mark 5 in .308 with this factory muzzle break. Accubreak makes perfect brakes. Now I want one on everything. So does my wife.

I installed one of these on a Mark V Hunter in .308. Not that you need a brake on one of these guns, but it is only six pounds without scope. I zeroed it while I was waiting on the brake. It was low to moderate at best recoil. Got it sighted in quickly, then shot it again with the brake. What a difference. It now feels like shooting a .243 or maybe even a .223. I could shoot it all day. Very pleased with this brake and the fit and finish is impeccable. Normal Weatherby stuff.

I recently purchased a Weatherby Mark V Hunter 7mm. Rem mag. I shot it three times without the Accubrake ST, the recoil was average for a 7mm. Then I attached the Accubrake ST. It was amazing how much it reduced the recoil! It fit perfectly and looks great. I would highly recommend this product! As with all Weatherby rifles and accessories it is high quality,

7mm Rem isn’t enough recoil to really need a brake but this definitely makes it more pleasant. It cut enough recoil that I would have no problem letting my wife shoot it instead of her 6.5 CM if the situation called for it. Everybody shoots better with less recoil, just get one.

I cannot recommend this enough. 300 Weatherby definitely has a bite to it, manageable but not enjoyable. I broke and sighted my Mark V in without the muzzle brake and was left with a sore and bruised shoulder. After I decided to purchase this muzzle brake, I can barely feel the recoil. I felt like this had even less recoil than my 7mm-08. It also fits the rifle perfectly, as you’d expect. Overall, I couldn’t be happier.
