Ahoy,
Purchased one of these for my RPR:
http://shopruger.com/Ruger-Precision-Rifle-Hybrid-Muzzle-Brake/productinfo/90590/
Before I cop a barrage of - why do you need a brake, p**sy?
Because I've never used one before
The gun jumps vertically off-target with a bipod
Also to see if there is any truth to the brake stabilsing the bullet in flight
Now, I've never fitted a brake before, is hand tightening one of these fine?
