At STR we have an on site shop located next to the 50mtr roof covered benchrest range. Scopes can be viewed in hand. Have a look at the scopes first. Test to see if the reticle is suitable to your needs and has sufficient mapping points for the type of gun and shooting you do, check to see if the magnification is sufficient, check to see if the scope and mounts allow for correct positioning for optimum eye relief. These are all critical factors when buying a rifle scope. Gunslip size is critical according to size of your rifle rig. Your welcome to call in, receive the right fitment and personal choice. I work full time on an airgun shooting range and have 11 years of experience.
