For those folks that are getting geared up to give FT hunter class a try, and your gun of choice is a break-barrel springer - a little tip. Before you mount that pretty, new, adjustable objective scope, make sure that the objective focus ring is set to it's minimum range setting - ie 10 yards. The reason for this is, as you adjust the AO ring, the scope length will change, and typically, at the lowest AO setting, the scope will be it's longest.

Why you ask? When setting your scope's eye relief, especially with a barrel-cocking gun, you have to be careful that the breech block does not contact the AO ring of the scope when all is finally snugged down - especially with the longer scopes. What I have seen in the past, and again just recently, is someone installs their scope with the AO ring set at 50 or 100 yards (as it came out of the box), and leaves what appears to be adequate clearance to the breech block. They then proceed to cock the gun, insert a pellet, close the breech, sight on their target, adjust the AO ring down to 10 yards, effectively lengthening their scope, and fire the first test shot. They then go to reload, and break open the barrel, at which time the breech block now contacts the bottom of the AO ring, and depending upon how hard one strikes the barrel to crack it open, can cause irrepairable damage to their scope - even kinking the tube at the forward mount.

"An ounce of prevention".... :wink:

Thanks for the heads up Suprmatic... :D
Never really owned a scope long enough to be concerned with reaching way out to the breech block, but these FT style scope are generally longer then the typical 3-9X42mm I'm used to... :shock: :lol:

Good post! Something I may not have considered...until it was too late! :oops:
Another reason I stick to fixed barrels though... :)

That is a great post, Suprmatic. This is exactly the kind of information we need. Good show!
