Scope Mounting | Getting the Correct Height
Mounting your scope with this method, can ensure you use the right parts and sizes. There are many different ways to mount a scope to your rifle, in this case we are using a Picatinny Rail with Picatinny Rings system.
Step 1: Find out what parts you need. With your rifle, position your scope over the rifle with the desired eye relief.
Step 2: Using the eye relief position you've acquired, put the scope as low as possible to the barrel without actually allowing it touch. Then measure the height from the rifle action to the bottom of the scope tube (this is BH). This will be the minimum height for your mounting parts. Picatinny Rails are usually between 5-10mm, plus your Scope Rings, which are available in a wide range of heights from 5mm right up to 22mm.
Step 3: Once you have acquired a minimum height for your mounts, you can order the parts and fit them. First of all, you fit the Picatinny rail (usually between 5-10mm high). Recknagel and Contessa produce a wide range of Picatinny Rails, pre drilled to fit straight to your rifle.
Step 4: Now your Picatinny Rail is fitted and secure, fit your Scope Rings. Recknagel Scope Rings come in a number of different heights and styles, including Tri-Nut or Quick Detachable. The height of your scope rings plus the height of your Picatinny Rail should measure more than the minium height of barrel relief. Start by unscrewing the top from the bottom and proceed to place the Ring bottoms onto your rail in the correct position and then secure them on.
Step 5: Place your scope onto the Ring bottoms and adjust the position for your desired eye relief. Also adjust to make sure the cross hairs are aligned correctly before you fix the ring tops.
Step 6: You can now place the rings tops over the scope tube and tighten to the ring bottoms. You should ensure they are fitted securely, but never over tighten as this can result in damage to either your scope or rings. Your scope is now mounted at a low height from the barrel and ready for testing.
