[QUOTE="Fiftydriver, post: 2804723, member: 10"] many think its a waste of money, when using my PK brakes, especially on this class of rifle with heavy scopes its almost a requirement to keep scope solidly in place long term. When i first started building these rifles, we had serious issues with the rails slipping on the receiver. This issue showed up as increased vertical stringing at long range, most notable past 800 yards. Pinned the rails to the receiver and solved that issue, however, solving that problem put even more stress on the ring to rail contact. still experienced vertical stringing. Tried many things but positioning two rings forward in the rail slot to control recoil energy and two rings to the rear of the rail slot to support the negative G forces generated by the muzzle brake solved this slippage issue. adding any costing to the metal surfaces exaggerates the problem. On these rifles again, pretty much a requirement but also relatively cheap insurance to know your optical system will never slip. it is more then just slapping 4 rings on the rail, mounted in a very specific and purposeful way.
