The rail in its cross-section is curved, hence the name S&B Convex rail. Schmidt and Bender have their very own solution when it comes to mounting a rifle scope to a firearm without the use of purpose made rings.
To mount the scope to the firearm first you have to properly insert the small convex metal adapters into the prepared slot at the bottom of the rifle scope. The next step is to attach this setting to a concave base and securely tightened. The two pieces will align to one and another due to their overlapping shape (convex – concave) and because of the grooves and perpendicular crests which at the end form the very impressive recoil stop. The recoil stop is as if it is made out of an array of tiny teeth that grab into themselves when they are subjected to the shooting forces. This kind of recoil is a result of friction caused by the grinding of the teeth. The only mounting solution that does not transmit the recoil by positive engagement is the Swarovski SR rail.
Mounting with a scope rail solutions is always the preferred way over the mounting with rings and in the future most of the European premium rifle scopes producers will exclusively use this approach. We are waiting on the first scope that will be produced with mounting rail only (apart from Zeiss Diarange which contains laser and cannot be mounted with rings at all).
When mounting with a rail you always get a perfect horizontal level as the reticle is aligned with the rail. Rings can leave marks on the main tube, but not only superficial marks, the structural integrity of the rifle scope can be compromised thus leaving the user with a corrupted image and tracking problems.The scopes that are mounted with the use of rail are lees subjected to recoil shocks and can withstand endless shots of almost any caliber Torque values for tightening the mounting elements in the scope rail should be between 4-5Nm.Scroll down to products
