How to se­cure your scope to your ri­fle? Our guru ad­vises

Air Gunner - - Contents -

D ear Guru I’ve got and new scope and mounts and I’m a bit wor­ried about fit­ting them to my new ri­fle. I’ve been told that if you don’t do the screws up tightly enough, the scope will slip and get scratched, but if you do them up too tightly, you’ll dam­age the scope by crush­ing it. How am I sup­posed to know what is tight enough? JAMIE Hello Jamie You’re not alone with this worry be­cause mak­ing a mis­take with equip­ment like this can be ex­pen­sive. A good rule is to fol­low any man­u­fac­turer’s in­struc­tions that come with your prod­ucts. Next, en­sure that any tools, such as the Allen keys you’ll need, are in good con­di­tion. Badly worn or rounded tips could dam­age the bolt heads, so re­place them be­fore you start.

I was al­ways taught that an ‘ L’ shaped Allen key was de­signed clev­erly be­cause if you use the long end in the socket head and short end as the lever, you’ll al­most cer­tainly ap­ply the right amount of torque to the screw. It’s al­most im­pos­si­ble to over- tighten a screw this way. It sur­prises many peo­ple that the screws don’t need to be any tighter than this, even on re­coil­ing ri­fles.

I’ve used this tech­nique for over 30 years and I’ve never had a prob­lem. How­ever, I have seen scope body tubes crushed and creased by peo­ple who have mas­sively over- tight­ened mount rings, in the past. The scopes still worked, but if you ever wanted to sell one, I doubt any­body would buy it from you with that kind of phys­i­cal dam­age.

Us­ing the Allen key this way gives you all the lever­age you need
