[QUOTE="Fiftydriver, post: 2664990, member: 10"] If there is no muzzle brake then there will be no ring slippage as there is only positive g forces produced when the rifle is fired. If however there is a quality muzzle brake, the negative g forces can cause the rings to slip on on the rail. Very few rings are a perfect fit in the rail slots. Most rings can be slide back and forth between the rail slots. When a rifle is fired, the recoil energy forces the rifle backward, as such so is the rail base and rings and finally into scope. Once the bullet passes through the muzzle brake, the rifle is dramatically decelerated. The base, rings and scope want to continue in their rearward movement and will unless they are physically prevented from doing so. now, many muzzle brakes are not effective enough to cause this, however most quality modern partition style brakes like my Painkiller brakes certainly cause this problem. The lighter the rifle, the worse it is, the heavier the scope, the worse it is. As such there must be ring to rail support for positive and Negative g forces to keep a scope solidly in place. this is the main reason i always use two sets of nightforce ultralight tactical rings on my Raptor LRSS rifles in my wildcats over 7mm Allen Mag and use three rings on my big Stalker magnum rifles. on the Raptor, 2 rings are positioned to control recoil energy (positive g forces) and two rings are positioned to control negative G forces. Best method to keep optics solidly in place permanently. With my Stalkers, two rings support recoil, one negative g forces. again, with some brake designs such as the radial port brakes, this is not an issue but highly effective brakes in the right rifle/scope combo can cause real issues.
